+**Be aware of billing charges for running the cluster.**
 
-Space Agon has been tested on this cluster size (nodes and machine types), but a small cluster may be sufficient for your use.    
-Don't leave the cluster running when you're not using it if you're concerned about cost. See [pricing](https://cloud.google.com/kubernetes-engine/pricing) for more.
+Space Agon is intended to run on [Google Kubernetes Engine (GKE)](https://cloud.google.com/kubernetes-engine) and has been tested with the configured cluster size.   
+Leaving the cluster running may incur your cost. You need to be responsible for the cost.

+## Develop Applications
+
+In case testing your original match making logics, [`skaffold`](https://skaffold.dev/) can help you debug your applications. 
+
+### Setup
+
+1. Create a space-agon k8s cluster.
+1. [Install `skaffold`](https://skaffold.dev/docs/install/) if you haven't. 
+1. Run `make skaffold-setup` on the project root to make a `skaffold.yaml`
+
+Now you're ready to run `skaffold` commands.
+
+### Debug
+
+Once you create a `skaffold.yaml`, you can run `skaffold` commands.
+
+You can check your own logic and debug.
+
+```bash
+# Build space-agon images with Cloud Build
+skaffold build 
+
+# Run Applicaitons in the space-agon cluster for debugging.
+skaffold dev
+```
+
+Modifying applications during `skaffold dev` triggers Build and Deploy automatically. For more commands and details, visit [`skaffold`](https://skaffold.dev/).
