 # 水 mizu
-standalone web app 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.
 
 ## Download

+SHA256 checksums are available on the [Releases](https://github.com/up9inc/mizu/releases) page.
 
+### Development (unstable) build
+Pick one from the [Releases](https://github.com/up9inc/mizu/releases) page.
+
+## How to run
 
 1. Find pod you'd like to tap to in your Kubernetes cluster
-2. Run `mizu --pod podname`
+2. Run `mizu tap PODNAME` or `mizu tap REGEX` 
 3. Open browser on `http://localhost:8899` as instructed .. 
 4. Watch the WebAPI traffic flowing ..
+5. Type ^C to stop
+
+## Examples
+
+Run `mizu help` for usage options
+
+
+To tap specific pod - 
+``` 
+ $ 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 - 
+``` 
+ $ kubectl get pods 
+ NAME                            READY   STATUS    RESTARTS   AGE
+ carts-66c77f5fbb-fq65r          2/2     Running   0          20m

+
+ $ mizu tap "^ca.*"
+ +carts-66c77f5fbb-fq65r
