+# CONTRIBUTE
+We welcome code contributions from the community.
+Please read and follow the guidelines below.
+
+## Communication
+* Before starting work on a major feature, please reach out to us via [GitHub](https://github.com/up9inc/mizu), [Slack](https://join.slack.com/share/zt-u6bbs3pg-X1zhQOXOH0yEoqILgH~csw), [email](mailto:mizu@up9.com), etc. We will make sure no one else is already working on it. A _major feature_ is defined as any change that is > 100 LOC altered (not including tests), or changes any user-facing behavior
+* Small patches and bug fixes don't need prior communication.
+
+## Contribution requirements
+* Code style - most of the code is written in Go, please follow [these guidelines](https://golang.org/doc/effective_go)
+* Go-tools compatible (`go get`, `go test`, etc)
+* Unit-test coverage can’t go down ..
+* Code must be usefully commented. Not only for developers on the project, but also for external users of these packages
+* When reviewing PRs, you are encouraged to use Golang's [code review comments page](https://github.com/golang/go/wiki/CodeReviewComments)

+# Kubernetes permissions for MIZU  
+
+This document describes in details all permissions required for full and correct operation of Mizu
+
+We broke down this list into few categories:
+- Required - what is needed for `mizu` to run properly on your k8s cluster
+- Optional - permissions needed for proper name resolving for service & pod IPs 
+   - addition required for policy validation 
+ 
+
+
+# Required permissions
+
+Mizu needs following permissions on your Kubernetes cluster to run properly
+
+```yaml
+- apiGroups:
+  - ""
+  resources:
+  - pods
+  verbs:
+  - list
+  - watch
+  - create
+  - delete
+- apiGroups:
+  - ""
+  resources:
+  - services
+  verbs:

+  - create
+  - delete
+- apiGroups:
+  - ""
+  resources:
+  - services/proxy
+  verbs:
+  - get
+```
+
+## Permissions required for service / pod name resolving (opt)
+
+Optionally, for proper resolving of IP addresses to Kubernetes service name, Mizu needs below permissions:
+
+```yaml
+- apiGroups:
+  - ""
+  resources:
+  - pods
+  verbs:
+  - get
+  - list

+
+## Permissions for Policy rules validation feature (opt)
+
+Optionally, in order to use the policy rules validation feature, Mizu requires the following additional permissions:
+
+```yaml
+- apiGroups:
+  - ""
+  resources:
+  - configmaps
+  verbs:
+  - get
+  - create
+  - delete
+```
+
+- - -
+
+## Namespace-Restricted mode
+
+Alternatively, in order to restrict Mizu to one namespace only (by setting `agent.namespace` in the config file), Mizu needs the following permissions in that namespace:
+
+```yaml
+- apiGroups:
+  - ""
+  resources:
+  - pods
+  verbs:
+  - get
+  - list
+  - watch
+  - create
+  - delete
+- apiGroups:
+  - ""
+  resources:

+  - create
+  - patch
+  - delete
+- apiGroups:
+  - ""
+  resources:
+  - services/proxy
+  verbs:
+  - get
+```
+
+### Name resolving in Namespace-Restricted mode (opt)
+
+To restrict Mizu to one namespace while also resolving IPs, Mizu needs the following permissions in that namespace:
+
+```yaml
+- apiGroups:
+  - ""

+# The API Traffic Viewer for Kubernetes
+
+A simple-yet-powerful API traffic viewer for Kubernetes to help you troubleshoot and debug your microservices. Think TCPDump and Chrome Dev Tools combined
+
+![Simple UI](assets/mizu-ui.png)
+
+## Features
+
+- Simple and powerful CLI
+- Real-time view of all HTTP requests, REST and gRPC API calls
+- No installation or code instrumentation
+- Works completely on premises

-## How to run
+## Prerequisites
+1. Set `KUBECONFIG` environment variable to your Kubernetes configuration. If this is not set, Mizu assumes that configuration is at `${HOME}/.kube/config`
+2. `mizu` assumes user running the command has permissions to create resources (such as pods, services, namespaces) on your Kubernetes cluster (no worries - `mizu` resources are cleaned up upon termination)
 
-1. Find pod you'd like to tap to in your Kubernetes cluster
-2. Run `mizu tap PODNAME` or `mizu tap REGEX` 
-3. Open browser on `http://localhost:8899` as instructed .. 
-4. Watch the WebAPI traffic flowing ..
+For detailed list of k8s permissions see [PERMISSIONS](PERMISSIONS.md) document
+
+
+## How to Run
+
+1. Find pods you'd like to tap to in your Kubernetes cluster
+2. Run `mizu tap` or `mizu tap PODNAME`  
+3. Open browser on `http://localhost:8899/mizu` **or** as instructed in the CLI
+4. Watch the API traffic flowing
 5. Type ^C to stop
 
 ## Examples
 
 Run `mizu help` for usage options

+## Configuration
+
+Mizu can work with config file which should be stored in ${HOME}/.mizu/config.yaml (macOS: ~/.mizu/config.yaml) <br />
+In case no config file found, defaults will be used <br />
+In case of partial configuration defined, all other fields will be used with defaults <br />
+You can always override the defaults or config file with CLI flags
+
+To get the default config params run `mizu config` <br />
+To generate a new config file with default values use `mizu config -r`
+
+### Telemetry
+
+By default, mizu reports usage telemetry. It can be disabled by adding a line of `telemetry: false` in the `${HOME}/.mizu/config.yaml` file
+
+
+## Advanced Usage
+
+### Namespace-Restricted Mode
+
+Some users have permission to only manage resources in one particular namespace assigned to them
+By default `mizu tap` creates a new namespace `mizu` for all of its Kubernetes resources. In order to instead install
+Mizu in an existing namespace, set the `mizu-resources-namespace` config option
+
+If `mizu-resources-namespace` is set to a value other than the default `mizu`, Mizu will operate in a
+Namespace-Restricted mode. It will only tap pods in `mizu-resources-namespace`. This way Mizu only requires permissions
+to the namespace set by `mizu-resources-namespace`. The user must set the tapped namespace to the same namespace by
+using the `--namespace` flag or by setting `tap.namespaces` in the config file
+
+Setting `mizu-resources-namespace=mizu` resets Mizu to its default behavior
+
+### User agent filtering
+
+User-agent filtering (like health checks) - can be configured using command-line options:
+
+```shell
+$ mizu tap "^ca.*" --set ignored-user-agents=kube-probe --set ignored-user-agents=prometheus
++carts-66c77f5fbb-fq65r
++catalogue-5f4cb7cf5-7zrmn
+Web interface is now available at http://localhost:8899
+^C
+
+```
+
+Any request that contains `User-Agent` header with one of the specified values (`kube-probe` or `prometheus`) will not be captured
+
+### API Rules validation
+
+This feature allows you to define set of simple rules, and test the API against them.
+Such validation may test response for specific JSON fields, headers, etc.
+
+Please see [API RULES](docs/POLICY_RULES.md) page for more details and syntax.
+
+
+## How to Run local UI
+
+- run from mizu/agent `go run main.go --hars-read --hars-dir <folder>`
+
+- copy Har files into the folder from last command
+
+- change `MizuWebsocketURL` and `apiURL` in `api.js` file
+
+- run from mizu/ui - `npm run start`
+
+- open browser on `localhost:3000`

-There are some extra flags defined in code that will show up in `./mizu --help`, these are non functional stubs for now
-
-## Installation
-Make sure your go version is at least 1.11
-1. cd to `mizu/cli`
-2. Run `go mod download` (may take a moment)
-3. Run `go build mizu.go`
-
-Alternatively, you can build+run directly using `go run mizu.go {pod_name_regex}`
-
-
-## Known issues
-* mid-flight port forwarding failures are not detected and no indication will be shown when this occurs
