+# 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

+## Permissions required for service / pod name resolving (opt)

+## 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 ${HOME}/.mizu/config.yaml file
+
+## Advanced Usage
+
+### Namespace-Restricted Mode
+
+Some users have permission to only manage resources in one particular namespace assigned to them
+By default `mizu tap` creates a new namespace `mizu` for all of its Kubernetes resources. In order to instead install
+Mizu in an existing namespace, set the `mizu-resources-namespace` config option
+
+If `mizu-resources-namespace` is set to a value other than the default `mizu`, Mizu will operate in a
+Namespace-Restricted mode. It will only tap pods in `mizu-resources-namespace`. This way Mizu only requires permissions
+to the namespace set by `mizu-resources-namespace`. The user must set the tapped namespace to the same namespace by
+using the `--namespace` flag or by setting `tap.namespaces` in the config file
+
+Setting `mizu-resources-namespace=mizu` resets Mizu to its default behavior
+
+### User agent filtering
+
+User-agent filtering (like health checks) - can be configured:
+
+Any request that contains one of those values in the user-agent header will not be captured
+
+```bash
+$ 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

-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
