+## 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 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.
+
+
+## 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
