+## About KubeVela
+
+KubeVela project is initialized and maintained by the cloud native community since day 0 with [bootstrapping contributors from 8+ different organizations](https://github.com/oam-dev/kubevela/graphs/contributors). We intend for KubeVela to have a open governance since the very beginning and donate the project to neutral foundation as soon as it's released. 
 
 This doc explains how to set up a development environment, so you can get started
 contributing to `kubevela` or build a PoC (Proof of Concept).

-# KubeVela Design
-
-This document is the detailed design and architecture of the KubeVela being built in this repository.
-
-> All the diagram in this documentation could be found in [this slides](https://docs.google.com/presentation/d/1Y3gnKrd7fUZGgee7Ia9vBsRIYhcZLQwMUCDkk1RJvQc/edit?usp=sharing).
-
-## Overview
-
-KubeVela is a simple, complete, but highly extensible cloud native application platform based on Kubernetes and Open Application Model (OAM). KubeVela intends to bring application-centric experience to its end users and democratize building cloud native application platforms for platform engineers.
-
-## User Stories
-
-As a end user (e.g. application developers, operators etc) of the platform, I only want to focus on coding my business logic and ship them to various environments at ease. Let's say:
-- Here's my source code.
-- Here's my application configuration (described in end user PoV).
-- Deploy it in test environment.
-- Deploy it in production environment.
-- Monitoring, debugging, rollout/rollback the application.
-- Dockerfile is fine, but please keep it simple. 
-
-As a platform engineer, I want to build a easy-to-use platform for my end users. In detail, the platform should be:
-- Heroku-like (_in terms of both user experience and functionality_). 
-  - and I prefer to build my own version with OSS tools, particularly, with Kubernetes (for obvious reason).
-- Easy to build. 
-  - I am too busy to reinvent any wheel, I want to reuse every capability in Kubernetes community as possible,  with minimal effort. Writing some simple CRD and controllers is fine, but please, just the simple ones like copy-paste.
-- Powerful and highly extensible.
-  - I don't want to lock my users with restricted abstractions and capabilities like traditional PaaS or FaaS/Serverless. I love Kubernetes and what it has enabled. So in terms of capability, I hope my platform is fully open and has unlimited possibilities like Kubernetes itself, rather than another opinionated close system like traditional PaaS.
-
-
-## Core Principles
-
-In nutshell, the principles for KubeVela project are:
-
-- For end users, it out-of-the-box ships a fully featured PaaS-like experience, nothing special.
-- For platform builders, it works like a special Kubernetes "distro" or extensible PaaS core that could be used to build something more complex. It allows platform builders to ship any existing capabilities in cloud native ecosystem to end users with minimal effort, or develop a new capability at ease in a standardized and Kubernetes-native approach.
-
-## Design Details
-
-### 1. Application Centric
-
-The design of KubeVela intends to make users think in terms of application, not containers or infrastructure. 
-
-Lacking application context impacts the user experience and significantly raised the bar to adopt cloud native stack. We believe "application" is the natural mindset of developers and it's the core concept an application platform should expose.
-
-![alt](resources/app-centric.png)
-
-KubeVela intends to let developers push code, define application in developer facing primitives, and make daily operations as configurations of the application.  
-
-Thus, KubeVela choose to:
-1. Introduce "application" as first class citizen and main API.
-2. Build the whole system around "application", i.e. model capabilities of Kubernetes as application configuration, with clarity and manageability.
-
-#### Solution
-
-Instead of creating a in-house "application CRD", KubeVela adopts [Open Application Model (OAM)](https://github.com/oam-dev/spec) as its application definition, since OAM:
-1. Defines micro-services application by default.
-2. Can model operations as part of the application (i.e. `Trait`).
-2. Highly extensible: every workload and trait in OAM is a independent definition, no abstraction or capability lock-in.
-
-### 2. Capability Oriented Architecture
-
-To enable platform builders use KubeVela as the extensible "PaaS core", KubeVela intends to make its every capability a standalone "plug-in".
-
-![alt](resources/coa.png)
-
-For example, there are several "built-in" workload types in KubeVela such as `Web Service` or `Task`. It is by design that they are all independent CRD controllers that abstract Kubernetes built-in workloads and create Service automatically if needed. KubeVela itself is **NOT** aware of the specification or implementation of these workload types.
-
-This means platform builders are free to bring their own workload types by simply install a CRD controller, or even just reference a k8s built-in resource like StatefulSet as new workload type.
-
-Similarly, all the "built-in" operations such as `scaling` or `rollout` (i.e. "traits" in KubeVela) are also independent CRD controllers which are **NOT** bound with specific workload types. Platform builders are free to bring their own traits implementations by simply providing a CRD controller, reference a k8s built-in resource like `HPA` or `NetworkPolicy` as trait is also possible.
-
-This loosely coupled design of KubeVela adopts the idea of Capability Oriented Architecture (COA), i.e. instead of creating a close system like traditional PaaS, KubeVela intends to become an application-centric framework to connect end users with underlying infrastructure capabilities.
-
-#### Solution
-
-We decide to build KubeVela core with [OAM Kubernetes runtime](https://github.com/crossplane/oam-kubernetes-runtime) which already implemented the building block features such as standalone workload type and trait controllers. Whether a given trait could work with certain workload types is also clarified as `appliesTo` field of trait definition. For platform builders, OAM Kubernetes Runtime also provided a [lightweight library](https://github.com/crossplane/oam-kubernetes-runtime/blob/2be3900a3817aed570de9ec353e6ab0b50e100f0/pkg/controller/v1alpha2/core/traits/manualscalertrait/manualscalertrait_controller.go#L42) to implement trait controller so it doesn't need to care about workload kinds.
-
-##### Capability Register and Discovery
-
-KubeVela leverages [OAM definition objects](https://github.com/oam-dev/spec/blob/master/4.workload_definitions.md) to register and discover workloads and traits:
-
-
-```console
-$ kubectl apply -f workload-definition.yaml # register a new workload type
-$ kubectl apply -f trait-definition.yaml # register a new trait
-```
-
-Note that OAM definition objects only care about API resource, not including the controllers. Thus KubeVela intends to include a **CRD registry** so whenever a new API resource is installed as workload or trait, KubeVela could install its controller automatically from the registry. That of course means we envision the CRD registry could register a CRD and Helm chart (which contains the manifest of the controller). In practice, we are currently evaluating RedHat's Operator Lifecycle Manager (OLM) but no the final conclusion yet.
-
-##### Cloud Services Integration
-
-For capabilities like cloud services, KubeVela intends to leverage Kubernetes as the universal control plane so [Crossplane](https://github.com/crossplane/crossplane) core will be used to register cloud services as workload types.
-
-
-### 3. Extensible User Interface
-
-KubeVela is built with Kubernetes and OAM also adopts Kubernetes API resource model. So in nutshell, **ALL** functionalities of KubeVela core are able to be consumed by simple `kubectl`, for example:
-
-```yaml
-$ kubectl apply -f frontend-component.yaml # create frontend component
-$ kubectl apply -f backend-component.yaml # create backend component
-$ kubectl apply -f application-config.yaml # assign operational traits to components
-```
-
-However, Kubernetes API should not be the end game. Declarative YAML objects are great to build platforms like KubeVela with but when directly exposed to end users, it creates heavy mental burden and high learning curve. For example, even with highest level abstraction, the default [containerized workload schema](https://github.com/oam-dev/spec/blob/master/core/workloads/schema/containerized_workload.md) of OAM still has dozens fields to learn with many rough edges to be aware.
-
-Thus KubeVela intends to introduce a lightweight user facing layer on top of its Kubernetes API objects with following goals in mind:
-
-- Shorten the learning curve of new developers. Most capabilities in KubeVela are developed by big
-companies that run very complex workloads. However, for the bigger developer community, the new user facing layer will provide a much simpler path to on-board KubeVela.
-- Developers can describe their applications and behavior of their components without making assumptions on availability of specific Kubernetes API. For instance, a developer will be able to model auto-scaling needs without referring to the CRD of auto-scaling trait.
-- Provides a single source of truth of the application description. The user facing layer allows developers to work with a single artifact to capture the application definition. This artifact is the definitive truth of how the application is supposed to look like. It simplifies administrative tasks such as change management. It also serves as an anchor for application truth to avoid configuration drifts during operation.
-- Highly extensible. For example, when a new workload type or trait is installed, the end users could access this new capability directly from user interface layer, no re-compile or re-deploy of KubeVela is required.
-
-#### Solution
-
-We concluded above requirements of the user interface layer as introducing a modeling language on top of the existing model objects. With this context, we decide to adopt [CUElang](https://github.com/cuelang/cue) as the modeling language of KubeVela. In detail, every workload or trait definition will inline a cue template as the contract between user and Kubernetes API object.
-
-However, we don't assume users need to learn or write CUElang directly. Instead, the reason we choose CUElang is it's just perfect to help us create developer facing tools based on it. Thus, KubeVela introduced three most common tools based to CUElang for developers to use:
-
-1. A command line tool.
-2. A GUI dashboard.
-3. A Docker Compose style `appfile`.
-
-An example for `vela cli`:
-
-```console
-$ vela comp deploy frontend -t webservice --image oamdev/testapp:v1 --port 80 --app helloworld
-```
-
-The `-t webservice --image oamdev/testapp:v1 --port 80` arguments are not hard coded, they are schema defined by in-line CUE template of `WebService` workload definition.
-
-The `appfile` is essentially a YAML version of command line tool so we can support more complex and serious scenarios by simply running `$ vela up hello-world.yaml`:
-
-```yaml
-version: "1.0-alpha.1"
-
-name: helloworld
-
-services:
-  express-server:
-    type: webservice # workload type
-    build:
-      docker:
-        file: Dockerfile
-        context: .
-
-    image: oamdev/testapp:v1
-    cmd: ["node", "server.js"]
-    ports:
-      - 8080:80
-    env:
-      - FOO=bar
-
-    scale: # scaling trait
-      replica: 2
-      auto:
-        range: "1-10"
-        cpu: 80
-        qps: 1000
-
-    canary: # canary trait
-      step: 5
-      headers:
-        - "foo:bar.*"
-
-  redis:
-    image: oamdev/redis
-
-secrets:
-  my-secret: /local-path/my-secret # load local file into k8s secret
-```
-
-The schema of above `appfile` is not hard coded, they are defined by in-line CUE templates of `WebService` workload definition, `Scaling` trait definition and `Canary` trait definition.
-
-We will skip the example of dashboard, but similarly, the schema of GUI forms are defined by in-lined CUE template of definition objects.
-
-## Architecture
-
-![alt](resources/arch.png)
-
-From highest level, KubeVela is composed by only two components:
-
-### 1. User interface layer
-Including: `cli`, `dashboard`, `appfile`, they are all client side tools to provide developer facing abstractions by leveraging CUElang based parametering and templating.
-### 2. KubeVela core
-Including:
-  - [OAM Kubernetes runtime](https://github.com/crossplane/oam-kubernetes-runtime) to provide application level building blocks such as `Component` and `Application` etc.
-  - [Built-in workload and trait controllers](https://github.com/oam-dev/kubevela/tree/master/pkg/controller/v1alpha1) to implement core capabilities such as `webservice`, `route` and `rollout` etc.
-  - Capability Management: manage features of KubeVela following Capability Oriented Architecture. 
-    - Every feature of KubeVela is a "addon", and it is registered by Kubernetes API resource (including CRD) leveraging OAM definition objects.
-    - CRD Registry: register controllers of Kubernetes add-ons and discover them by CRD. This will enable automatically install controllers/operators when CRD is missing in the cluster.

 # KubeVela
 
-The Open Application Platform based on Kubernetes and Open Application Model (OAM).
+For developers, KubeVela is an easy-to-use tool that enables them to describe and ship their applications to Kubernetes with minimal effort.
 
-## Project Status
+For platform builders, KubeVela serves as a framework that empowers them to create developer facing yet highly extensible platforms at ease.
 
-:rotating_light: **Warning: this project is still a work in progress with lots of rough edges, please don't look inside unless you know what you are doing.**
+- Slack: [Discuss](https://cloud-native.slack.com/archives/C01BLQ3HTJA)
+- Gitter: [Community](https://gitter.im/oam-dev/community)
 
-KubeVela project is initialized and maintained by the cloud native community since day 0 with [bootstrapping contributors from 8+ different organizations](https://github.com/oam-dev/kubevela/graphs/contributors). We intend for KubeVela to have a open governance since the very beginning and donate the project to neutral foundation as soon as it's released. 
+> NOTE: KubeVela is still in early stage and iterating quickly. It's currently under preview release.
 
-## Purpose and Goal
+## Quick Start
 
-- For developers and operators
-  - KubeVela, as an out-of-box Cloud Native Application Management Platform, provides numerous workloads and operation tooling for application defining, deployment, scaling, traffic, rollout, routing, monitoring, logging, alerting, CI/CD and so on.
-- For platform builders
-  - KubeVela, as a highly extensible PaaS/Serverless Core, provides pluggable capabilities, an elegant way to integrate any workloads and operational capabilities (i.e. traits).
+Quick start guides are available on [this section](https://kubevela.io/#/en/quick-start).
 
-## Design and Architecture
+## Documentation
 
-Read more about [KubeVela's high level design and architecture](DESIGN.md).
-
-## Demo Instructions
-
-See the demo instructions below get a sense of what we've accomplished and are working on.
-
-## Install
-
-### Prerequisites
-- Kubernetes cluster running Kubernetes v1.15.0 or greater
-- kubectl current context is configured for the target cluster install
-  - ```kubectl config current-context```
-
-### Get the Vela CLI
-
-Download the `vela` binary from the [releases page](https://github.com/oam-dev/kubevela/releases). Unpack the `vela` binary and add it to `$PATH` to get started.
-
-```shell
-sudo mv ./vela /usr/local/bin/vela
-```
-
-### Install Vela Core
-
-```console
-$ vela install
-```
-This command will install vela core controller into your K8s cluster, along with built-in workloads and traits.
-
-## Using KubeVela
-
-After `vela install` you will see available workloads and traits.
-
-```console
-$ vela workloads
-NAME         	DEFINITION
-backend      	podspecworkloads.standard.oam.dev
-task         	jobs.batch.k8s.io
-webservice   	podspecworkloads.standard.oam.dev
-```
-
-```console
-$ vela traits
-NAME        	DEFINITION                        	APPLIES TO
-route       	routes.standard.oam.dev           	webservice,backend            	                                  
-scale       	manualscalertraits.core.oam.dev   	webservice,backend
-```
-
-### Create environment
-
-Before working with your application, you should prepare an deploy environment for it (e.g. test, staging, prod etc).
-
-```console
-$ vela env init demo --namespace demo --email my@email.com --domain kubevela.io
-ENVIROMENT demo CREATED, Namespace: demo, Email: my@email.com.
-```
-
-Vela will create a Kubernetes namespace called `demo` , with namespace level issuer for certificate generation using the email you provided.
-
-You could check the environment metadata in your local:
-
-```console
-$ cat ~/.vela/envs/demo/config.json
-  {"name":"demo","namespace":"demo","email":"my@email.com","domain":"kubevela.io","issuer":"oam-env-demo"}
-```
-
-
-### Create simple component 
-
-Then let's create application, we will use the `demo` environment.
-
-```console
-$ vela comp deploy mycomp -t webservice --image crccheck/hello-world --port 8000 --app myapp
-Creating AppConfig appcomp
-SUCCEED
-```
-
-### Create micro-services application
-
-Vela supports micro-services application by default thanks to Open Application Model.
-
-```console
-$ vela comp deploy db -t backend --image crccheck/hello-world --app myapp
-Creating App myapp
-SUCCEED
-```
-
-```console
-$ vela comp ls
-NAME  	APP  	WORKLOAD  	TRAITS	STATUS 	  CREATED-TIME
-db    	myapp	backend   	      	Deployed	2020-09-18 22:42:04 +0800 CST
-mycomp	myapp	webservice	      	Deployed	2020-09-18 22:42:04 +0800 CST
-```
-
-#### Under the hood
-
-In Kubernetes, vela creates an OAM application configuration named `myapp` to manage all related components.
-
-```console
-$ kubectl get appconfig -n demo
-  NAME    AGE
-  myapp   24s
-```
-
-```console
-$ kubectl get components -n demo
-  NAME     AGE
-  mycomp   24s
-  db       10s
-```
-
-Vela Core is responsible for managing the underlying Kubernetes resources linked with the components and application configuration above.
-
-```console
-$ kubectl get deployment -n demo
-  NAME     READY   UP-TO-DATE   AVAILABLE   AGE
-  mycomp   1/1     1            1           38s
-  db       1/1     1            1           20s
-``` 
-
-```console
-$ kubectl get svc -n demo
- NAME     TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)    AGE
- mycomp   ClusterIP   172.21.4.228   <none>        8080/TCP   49s
-```
-
-### Manage operational configurations of the application
-
-Vela leverages OAM trait system to manage operational configurations such as `scale`, `route`, `canary`, `autocale`etc in application centric approach.
-
-Let's take `route` as example.
-
-### `route`
-
-If you want to use `route`, please make sure you have [nginx-ingress controller[https://kubernetes.github.io/ingress-nginx/deploy/] in your cluster.
-
-```console
-$ vela route mycomp --app myapp
- Adding route for app mycomp
- Succeeded!
-```
-
-For now you have to check the public address manually (this will be fixed soon so `vela route` will return visiting URL as result):
-
-```console
-$ kubectl get ingress -n demo
-NAME                        HOSTS                ADDRESS         PORTS     AGE
-mycomp-trait-5b576c4fc      mycomp.kubevela.io   123.57.10.233   80, 443   73s
-```
-
-And after you configure the `kubevela.io` domain pointing to the public address above.
-
-Your application will be reached by `https://mycomp.kubevela.io` with `mTLS` automatically enabled.
-
-### Under the hood
-
-Vela will manage the underlying Kubernetes resource which implements the `route` trait.
-
-```console
-$ kubectl get routes.standard.oam.dev -n demo
-NAME                     AGE
-mycomp-trait-5b576c4fc   18s
-```
-
-`routes.standard.oam.dev` is a CRD controller which will manage ingress, domain, certificate etc for your application.
-
-### Check status
-
-
-Check the application:
-
-```console
-$ vela app show myapp
-  About:
-  
-    Name:      	myapp
-    Created at:	2020-09-18 22:42:04.191171 +0800 CST

-    mycomp	webservice	route
-```
-
-Check specific component:
-
-```console
-$ vela comp show mycomp
- About:
- 
-   Name:        	mycomp
-   WorkloadType:	webservice

-   route:
-     domain:	mycomp.kubevela.io
-     issuer:	oam-env-demo
-     name:  	route
-```
-
-```
-$ vela comp status mycomp
-  Showing status of Component mycomp deployed in Environment demo
-  Component Status:
-  	Name: mycomp  PodSpecWorkload(type) UNKNOWN APIVersion standard.oam.dev/v1alpha1 Kind PodSpecWorkload workload is unknown for HealthScope
-  	Traits
-  	    └─Trait/route
-  
-  Last Deployment:
-  	Created at: 2020-09-18 22:42:04 +0800 CST
-  	Updated at: 2020-09-18T22:51:11+08:00
-```
-
-### Delete application or component
-
-```console
-$ vela app ls
-myapp
-```
-
-```console
-$ vela comp ls
-NAME  	APP  	WORKLOAD  	TRAITS	STATUS 	CREATED-TIME
-db    	myapp	backend   	      	Deployed	2020-09-18 22:42:04 +0800 CST
-mycomp	myapp	webservice	route 	Deployed	2020-09-18 22:42:04 +0800 CST
-```
-
-```console
-$ vela comp delete db
-Deleting Component 'db' from Application 'db'
-```
-
-```console
-$ vela comp ls
-NAME  	APP  	WORKLOAD  	TRAITS	STATUS 	CREATED-TIME
-mycomp	myapp	webservice	route 	Deployed	2020-09-18 22:42:04 +0800 CST
-```
-
-```console
-$ vela app delete myapp
-Deleting Application "myapp"
-delete apps succeed myapp from demo
-```
-
-## Dashboard
-
-Vela has a simple client side dashboard for you to interact with (note it's still under development). The functionality is equivalent to the vela cli.
-
-```console
-$ vela dashboard
-```
-
-#### Auto-completion
-
-##### bash
-
-```console
-To load completions in your current shell session:
-$ source <(vela completion bash)
-
-To load completions for every new session, execute once:
-Linux:
-  $ vela completion bash > /etc/bash_completion.d/vela
-MacOS:
-  $ vela completion bash > /usr/local/etc/bash_completion.d/vela
-```
-
-##### zsh
-
-```console
-To load completions in your current shell session:
-$ source <(vela completion zsh)
-
-To load completions for every new session, execute once:
-$ vela completion zsh > "${fpath[1]}/_vela"
-```
-
-### Clean your environment
-
-```console
-$ helm uninstall kubevela -n vela-system
-release "kubevela" uninstalled
-```
-
-```console
-$ kubectl delete crd workloaddefinitions.core.oam.dev traitdefinitions.core.oam.dev  scopedefinitions.core.oam.dev
-customresourcedefinition.apiextensions.k8s.io "workloaddefinitions.core.oam.dev" deleted
-customresourcedefinition.apiextensions.k8s.io "traitdefinitions.core.oam.dev" deleted
-```
-
-```console
-$ rm -r ~/.vela

+# Apply-Once-Only: Apply workload/trait only when spec is changed
+
+- Owner: Yue Wang(@captainroy-hy), Jianbo Sun(@wonderflow)
+- Date: 11/24/2020
+- Status: Implemented
+
+## Intro
+When an ApplicationConfiguration is deployed, 
+vela-core will create(apply) corresponding workload/trait instances and keep them stay align with the `spec` defined in ApplicationConfiguration through periodical reconciliation. 
+
+If we run vela-core with `--apply-once-only` flag enabled, vela-core will never apply the workload and trait instance after they are applied once. Even if they are changed by others (e.g., trait controller, workload controller,etc). 
+Since the create operation is the only one apply operation occurring on workload/trait, we call this mechanism as `Apply Once Only`.
+
+## A Motivational Example
+Here is a scenario from production environment to demonstrate how `Apply Once Only` works.
+
+```yaml
+apiVersion: core.oam.dev/v1alpha2
+kind: ApplicationConfiguration
+metadata:
+  name: example-appconfig
+spec:
+  components:
+    - componentName: example-component
+---
+apiVersion: core.oam.dev/v1alpha2
+kind: Component
+metadata:
+  name: example-component
+spec:
+  workload:
+    apiVersion: apps/v1
+    kind: Deployment
+    spec:
+      ...
+      template:
+        spec:
+          containers:
+            - image: sample/app:1.0
+              name: sample-app
+```
+
+After deploying above ApplicationConfiguration, vela-core will create a Deployment with corresponding `PodTemplateSpec`. 
+
+In production env, it's possible to change the Deployment according to particular requirements, e.g., RolloutTrait, AutoscalerTrait,etc.
+Currently, we just use `kubectl` to simulate workload is changed bypass changing the ApplicationConfiguration. 
+Below cmd changes `spec.template.spec.containers[0].image` of the Deployment from `sample/app:1.0` to `sample/app:2.0`.
+```shell
+cat <<EOF | kubectl patch deployment example-deploy --patch
+spec:
+  template:
+    spec:
+      containers:
+      - name: sample-app
+        image: sample/app:2.0
+EOF
+```
+
+Above change will trigger recreate of Pods owned by the Deployment. 
+But vela-core will change it back to `sample/app:1.0` in the following reconciliation soon or late. 
+That's not what we expect in some scenarios.
+
+Instead, we hope vela-core ignore reconciling the workload we changed and leave them as what they are now until we change the `spec` of their parent ApplicationConfiguration .
+
+## Goals
+
+Add a startup parameter for vela-core controller to allow users choose whether to enable apply only once or not. 
+
+If enabled, workload/trait will be applied only one time for each resource generation (only when the corresponding appconfig/component is created or updated).
+After workload/trait created/updated and aligned to the generation of appconfig, vela-core will not apply them EXCEPT below situations:
+
+- The `spec` of ApplicationConfiguration is changed (new generation created)
+- The revision of Component is changed
+
+By default, the mechanism is disabled, vela-core will always reconcile and apply workload/trait periodically as usual.
+
+## Implementation
+
+In each round of reconciliation, vela-core compares below Labels & Annotations of existing workload/trait with newly rendered ones before applying.
+
+After deploying the ApplicationConfiguration in the motivational example, the Deployment created by vela-core will have such lables and annotations.
+
+
+```yaml
+apiVersion: apps/v1
+kind: Deployment
+metadata:
+  annotations:
+    deployment.kubernetes.io/revision: "1" 
+    app.oam.dev/generation: "1"
+  generation: 1
+  labels:
+    app.oam.dev/component: example-component
+    app.oam.dev/name: example-appconfig
+    app.oam.dev/resourceType: WORKLOAD
+    app.oam.dev/revision: example-component-v1
+  ...
+```
+
+- `annotations["app.oam.dev/generation"]:"1" ` refers to the generation of AppConfig
+- `labels["app.oam.dev/revision"]:"example-component-v1" ` refers to the revision of Component
+
+These crucial two are propogated from AppConfig and Component during reconciliation.
+Any change applied to the Deployment directly has no impact on these labels and annotations, e.g., change the Deployment spec just like what we do in the [motivational example](#a-motivational-example).
+If `--apply-once-only` is enabled, since no discrepancy is found on lables and annotations, 
+vela-core controller will ignore applying the Deployment and leave it as what it is at that moment.
+
+By contrast, changes on AppConfig (changing `spec` creates new generation) and Component (updating Component creates new revision) will change the value of these labels and annotations.
+For example, if we update the spec of AppConfig, newly rendered workload is supposed to contain such labels and annotations.
+
+```yaml
+apiVersion: apps/v1
+kind: Deployment
+metadata:
+  annotations:
+    deployment.kubernetes.io/revision: "1" 
+    app.oam.dev/generation: "2" # generation of AppConfig changed
+  generation: 1
+  labels:
+    app.oam.dev/component: example-component
+    app.oam.dev/name: example-appconfig
+    app.oam.dev/resourceType: WORKLOAD
+    app.oam.dev/revision: example-component-v1
+  ...
+```
+Since discrepancy is found, vela-core controller will apply(update) the Deployment with newly rendered one.
+Thus, the changes we made to the Deployment before will also be eliminated.
+
+The same mechanism also works for Trait as well as Workload.

+- If the name of TraitDefinition is different to that of Trait CRD
+
+The definition name `autoscale` is different to the trait name `autoscalers.standard.oam.dev`, we have two ways to compose ComponentTrait.
+
+```
+apiVersion: core.oam.dev/v1alpha2
+kind: TraitDefinition
+metadata:
+  name: autoscale
+spec:
+  definitionRef:
+    name: autoscalers.standard.oam.dev
+```
+
+1) Use label `trait.oam.dev/type`
+
+```
+apiVersion: core.oam.dev/v1alpha2
+kind: ApplicationConfiguration
+metadata:
+  name: example-appconfig
+spec:
+  components:
+    - componentName: example-component
+      traits:
+        - trait:
+            apiVersion: standard.oam.dev/v1alpha2
+            kind: Autoscalers
+            metadata:
+              labels:
+                trait.oam.dev/type: autoscale
+            spec:
+              replicaCount: 3
+```
+
+When rendering trait, the TraitDefinition could be retrieved by the label.
+
+2) Use `name` field
+
+```
+apiVersion: core.oam.dev/v1alpha2
+kind: ApplicationConfiguration
+metadata:
+  name: example-appconfig
+spec:
+  components:
+    - componentName: example-component
+      traits:
+        - trait:
+            apiVersion: standard.oam.dev/v1alpha2
+            kind: Autoscalers
+            name: autoscale
+            spec:
+              replicaCount: 3
+```
+
+The mutating handler will, at the very beginning,  convert `name:autoscale` to the labels above.
+
+In summary, among these two ways to compose ComponentTrait, using labeling is recommended.
+
+While in KubeVela, you don't need to worry about either `label` or `name`, just use command `vela TraitType` or `vela up` to attach the trait to
+a component.
+
+## Set the CR name in a friendly way
+
+Currently, we named all trait name in the format of `${ComponentName}-trait-${HashTag}`. This will lead to confusions
+when listing CRs of all Traits of a component. 
+
+In this proposal, we propose to change the naming rule to `${ComponentName}-${TraitDefinitionName}-${HashTag}`.
+
+For example, if the name of TraitDefinition is `autoscale`, we name the trait CR to `example-component-autoscale-xyzfa32r`.
+
+```
+apiVersion: core.oam.dev/v1alpha2
+kind: ApplicationConfiguration
+metadata:
+  name: example-appconfig
+spec:
+  components:
+    - componentName: example-component
+      traits:
+        - trait:
+            apiVersion: standard.oam.dev/v1alpha2
+            kind: Autoscalers
+            metadata:
+              labels:
+                trait.oam.dev/type: autoscale
+            spec:
+              replicaCount: 3
+```
+
+If the name is the same as the CRD name, like `manualscalertraits.core.oam.dev`, we name it to `example-component-manualscalertraits-rq234rrw`
+by choosing the first part.
+
+```
+apiVersion: core.oam.dev/v1alpha2
+kind: ApplicationConfiguration
+metadata:
+  name: example-appconfig
+spec:
+  components:
+    - componentName: example-component
+      traits:
+        - trait:
+            apiVersion: core.oam.dev/v1alpha2
+            kind: ManualScalerTrait
+            spec:
+              replicaCount: 3

+  name: manualscalertraits.core.oam.dev
+spec:
+  workloadRefPath: spec.workloadRef
+  definitionRef:
+    name: manualscalertraits.core.oam.dev
+```
+
+After OAM Kubernetes Runtime is upgraded, the old trait CR name `example-component-trait-uewf77eu` will stay unchanged for previous version compatibility.

+# How to upgrade to KubeVela
+
+What if I want to upgrade from [oam-kubernetes-runtime](https://github.com/crossplane/oam-kubernetes-runtime) to KubeVela? Here's a detailed guide!
+
+## For users who are using OAM runtime as standalone controller
+
+If you are using OAM Runtime as Standalone Controller, upgrading to KubeVela to KubeVela is very straight forward.
+
+Server-side KubeVela(We call it `vela-core` for convenience) now includes following **BUILT-IN** CRDs and controllers.
+
+| Type |  CRD   | Controller  | From |
+| ---- |  ----  | ----  | ----  |
+| Control Plane Object | `applicationconfigurations.core.oam.dev` | Yes | OAM Runtime |
+| Control Plane Object | `components.core.oam.dev` | Yes | OAM Runtime |
+| Workload Type | `containerizedworklaods.core.oam.dev` | Yes | OAM Runtime |
+| Scope | `healthscope.core.oam.dev` | Yes | OAM Runtime |
+| Trait | `manualscalertraits.core.oam.dev` | Yes | OAM Runtime |
+| Control Plane Object | `scopedefinitions.core.oam.dev` | No | OAM Runtime |
+| Control Plane Object | `traitdefinitions.core.oam.dev` | No | OAM Runtime |
+| Control Plane Object | `workloaddefinitions.core.oam.dev` | No | OAM Runtime |
+| Trait | `autoscalers.standard.oam.dev` | Yes | New in KubeVela |
+| Trait | `metricstraits.standard.oam.dev` | Yes | New in KubeVela |
+| Workload Type | `podspecworkloads.standard.oam.dev` | Yes | New in KubeVela |
+| Trait | `route.standard.oam.dev` | Yes | New in KubeVela |
+
+CRDs and Controllers in the table from 'OAM Runtime' are exactly the same to those in `oam-kubernetes-runtime`.
+So in KubeVela we have added 4 more new CRDs with controller. 
+
+### Option 1: I only want to have OAM control plane objects only, no additional traits and workload types.
+
+1. Find you deployment
+
+```shell script
+$ kubectl -n oam-system get deployment -l app.kubernetes.io/name=oam-kubernetes-runtime
+NAME                         READY   UP-TO-DATE   AVAILABLE   AGE
+oam-kubernetes-runtime-oam   1/1     1            1           62s
+```
+
+2. Update the deployment
+
+In this case, the deployment name of OAM runtime is `oam-kubernetes-runtime-oam`, let's edit it to update the image:
+
+```shell script
+$ kubectl -n oam-system edit deployment oam-kubernetes-runtime-oam
+```
+
+There are two changes:
+
+- update the image from `crossplane/oam-kubernetes-runtime:latest` to `oamdev/vela-core:latest`
+- add an args `- "--disable-caps=all"`, which will disable all additional workloads and traits built in vela-core described in the following table.
+
+| Type | Current KubeVela Additional CRD   |
+| ---- |  ----  |
+| Trait | `autoscalers.standard.oam.dev` |
+| Trait | `metricstraits.standard.oam.dev` |
+| Workload | `podspecworkloads.standard.oam.dev` |
+| Trait | `route.standard.oam.dev` |
+
+```yaml
+apiVersion: apps/v1
+kind: Deployment
+metadata:
+  name: oam-kubernetes-runtime-oam
+...
+      containers:
+        - name: oam
+          args:
+            - "--metrics-addr=:8080"
+            - "--enable-leader-election"
++           - "--disable-caps=all"
+-         image: crossplane/oam-kubernetes-runtime:latest
++         image: oamdev/vela-core:latest
+          imagePullPolicy: "Always"
+...
+```
+
+### Option 2: I want full featured KubeVela, including its built-in workload types and traits.
+
+1. Install Additional CRDs
+
+```shell script
+$ kubectl apply -f charts/vela-core/crds
+```
+
+2. Install Definition files
+
+```shell script
+$ kubectl apply -f charts/vela-core/templates/defwithtemplate
+```
+
+3. Create namespace, vela-core use `vela-system` as default
+
+```shell script
+$ kubectl create ns vela-system
+```
+
+4. Install Cert Manager
+
+```shell script
+$ kubectl apply -f charts/vela-core/templates/cert-manager.yaml
+```
+
+5. Install Vela Dependency ConfigMap
+
+```shell script
+$ kubectl apply -f charts/vela-core/templates/velaConfig.yaml
+```
+
+6. Delete your old oam-runtime deployment
+
+Find the running deployment.
+
+```shell script
+$ kubectl -n oam-system get deployment -l app.kubernetes.io/name=oam-kubernetes-runtime
+NAME                         READY   UP-TO-DATE   AVAILABLE   AGE
+oam-kubernetes-runtime-oam   1/1     1            1           62s
+```
+
+Delete the deployment found.
+
+```shell script
+$ kubectl -n oam-system delete deployment oam-kubernetes-runtime-oam
+```
+
+7. Install Certificate and Webhook for the new controller
+
+```shell script
+$ helm template --release-name kubevela -n vela-system -s templates/webhook.yaml charts/vela-core/ | kubectl apply -f -
+```
+
+8. Install the new controller
+
+```shell script
+$ helm template --release-name kubevela -n vela-system -s templates/kubevela-controller.yaml charts/vela-core/ | kubectl apply -f -
+```
+
+> TIPS: If you want to disable webhook, change 'useWebhook' to be 'false' in  `charts/vela-core/values.yaml`
+
+Then you have successfully migrate from oam-kubernetes-runtime to KubeVela.
+
+## For users who are importing OAM runtime as library
+
+If you are importing `oam-kubernetes-runtime` as library, you can update your import headers.
+
+Files are refactored as below:
+
+| OLD |  NEW   | Usage  |
+| ---- |  ----  | ----  |
+| `github.com/crossplane/oam-kubernetes-runtime/apis/core` | `github.com/oam-dev/kubevela/apis/core.oam.dev` | API Spec Code |
+| `github.com/crossplane/oam-kubernetes-runtime/pkg/controller` | `github.com/oam-dev/kubevela/pkg/controller/core.oam.dev` | OAM Controller Code |
+| `github.com/crossplane/oam-kubernetes-runtime/pkg/oam` | `github.com/oam-dev/kubevela/pkg/oam` | OAM Common Lib Code |
+| `github.com/crossplane/oam-kubernetes-runtime/pkg/webhook` | `github.com/oam-dev/kubevela/pkg/webhook/core.oam.dev` | OAM Webhook Code |

+# Rollout
+
+## Conflicts With
+
+### `Autoscale`
+
+When `Rollout` and `Autoscle` traits are attached to the same service, they two will fight over the number of instances during rollout. Thus, it's by design that `Rollout` will take over replicas control (specified by `.replicas` field) during rollout.
+
+> Note: in up coming releases, KubeVela will introduce a separate section in Appfile to define release phase configurations such as `Rollout`.
+
+## How `Rollout` works?
+
+`Rollout` trait implements progressive release process to rollout your app following [Canary strategy](https://martinfowler.com/bliki/CanaryRelease.html).
+
+In detail, `Rollout` controller will create a canary of your app , and then gradually shift traffic to the canary while measuring key performance indicators like HTTP requests success rate at the same time. 
+
+
+![alt](../../docs/resources/traffic-shifting-analysis.png)
+
+In this sample, for every `10s`, `5%` traffic will be shifted to canary from the primary, until the traffic on canary reached `50%`. At the mean time, the instance number of canary will automatically scale to `replicas: 2` per configured in Appfile.
+
+
+Based on analysis result of the KPIs during this traffic shifting, a canary will be promoted or aborted if analysis is failed. If promoting, the primary will be upgraded from v1 to v2, and traffic will be fully shifted back to the primary instances. So as result, canary instances will be deleted after the promotion finished.
+
+![alt](../../docs/resources/promotion.png)
+
+> Note: KubeVela's `Rollout` trait is implemented with [Weaveworks Flagger](https://flagger.app/) operator.
