-# 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
-

-## Permissions for Policy rules validation feature (opt)

-  - 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:

+## How to run
 
-## Kubeconfig & Permissions
-While `mizu`most often works out of the box, you can influence its behavior:
-
-1. [OPTIONAL] 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)
-
-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
+1. Find pod you'd like to tap to in your Kubernetes cluster
+2. Run `mizu PODNAME` or `mizu REGEX` 
+3. Open browser on `http://localhost:8899` as instructed .. 
+4. Watch the WebAPI traffic flowing ..
 
 ## Examples
-
-Run `mizu help` for usage options
-
-To tap all pods in current namespace - 
-``` 
- $ kubectl get pods 
- NAME                            READY   STATUS    RESTARTS   AGE
- carts-66c77f5fbb-fq65r          2/2     Running   0          20m
- catalogue-5f4cb7cf5-7zrmn       2/2     Running   0          20m
- front-end-649fc5fd6-kqbtn       2/2     Running   0          20m
- ..
-
- $ mizu tap
- +carts-66c77f5fbb-fq65r
- +catalogue-5f4cb7cf5-7zrmn
- +front-end-649fc5fd6-kqbtn
- Web interface is now available at http://localhost:8899
- ^C
-```
-
-
-To tap specific pod - 
-```bash
- $ kubectl get pods 
- NAME                            READY   STATUS    RESTARTS   AGE
- front-end-649fc5fd6-kqbtn       2/2     Running   0          7m
- ..
-
- $ mizu tap front-end-649fc5fd6-kqbtn
- +front-end-649fc5fd6-kqbtn
- Web interface is now available at http://localhost:8899
- ^C
-```
-
-To tap multiple pods using regex - 
-```bash
- $ kubectl get pods 
- NAME                            READY   STATUS    RESTARTS   AGE
- carts-66c77f5fbb-fq65r          2/2     Running   0          20m
- catalogue-5f4cb7cf5-7zrmn       2/2     Running   0          20m
- front-end-649fc5fd6-kqbtn       2/2     Running   0          20m
- ..
-
- $ mizu tap "^ca.*"
- +carts-66c77f5fbb-fq65r
- +catalogue-5f4cb7cf5-7zrmn
- Web interface is now available at http://localhost:8899
- ^C
-```
-
-## 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
