* Remove unnecessary fields and split `service` into `src.name` and `dst.name`

* Don't fall back to IP address but instead display `[Unresolved]` text

* Fix the CSS issues in the plus icon position and replace the separator `->` text with `SwapHorizIcon`

+
+## 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
+
+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
+ ..
 
-1. Find pod you'd like to tap to in your Kubernetes cluster
-2. Run `mizu --pod podname`
-3. Open browser on `http://localhost:8899` as instructed .. 
-4. Watch the WebAPI traffic flowing ..
+ $ 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 optionally work with a config file that can be provided as a CLI argument (using `--set config-path=<PATH>`) or if not provided, will be stored at ${HOME}/.mizu/config.yaml 
+In case of partial configuration defined, all other fields will be used with defaults <br />
+You can always override the defaults or config file with CLI flags
+
+To get the default config params run `mizu config` <br />
+To generate a new config file with default values use `mizu config -r`
+
+
+## Advanced Usage
+
+### Kubeconfig
+
+It is possible to change the kubeconfig path using `KUBECONFIG` environment variable or the command like flag
+with `--set kube-config-path=<PATH>`. </br >
+If both are not set - Mizu assumes that configuration is at `${HOME}/.kube/config`
+
+### 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
+
+For detailed list of k8s permissions see [PERMISSIONS](docs/PERMISSIONS.md) document
+
+### User agent filtering
+
+User-agent filtering (like health checks) - can be configured using command-line options:
+
+```shell
+$ mizu tap "^ca.*" --set tap.ignored-user-agents=kube-probe --set tap.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
+
+### Traffic validation rules
+
+This feature allows you to define set of simple rules, and test the traffic against them.
+Such validation may test response for specific JSON fields, headers, etc.
+
+Please see [TRAFFIC RULES](docs/POLICY_RULES.md) page for more details and syntax.
+
+### OpenAPI Specification (OAS) Contract Monitoring
+
+An OAS/Swagger file can contain schemas under `parameters` and `responses` fields. With `--contract catalogue.yaml`
+CLI option, you can pass your API description to Mizu and the traffic will automatically be validated
+against the contracts.
+
+Please see [CONTRACT MONITORING](docs/CONTRACT_MONITORING.md) page for more details and syntax.
+
+### Configure proxy host 
+
+By default, mizu will be accessible via local host: 'http://localhost:8899/mizu/', it is possible to change the host,
+for instance, to '0.0.0.0' which can grant access via machine IP address.
+This setting can be changed via command line flag `--set tap.proxy-host=<value>` or via config file:
+tap
+    proxy-host: 0.0.0.0
+and when changed it will support accessing by IP
+
+### Run in daemon mode
+
+Mizu can be run detached from the cli using the daemon flag: `mizu tap --daemon`. This type of mizu instance will run
+indefinitely in the cluster.
+
+For more information please refer to [DAEMON MODE](docs/DAEMON_MODE.md)

-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
