+## Development
+
+### When you work on core/wave-autoscale
+```bash
+# Run
+moon run controller:[test|run]
+
+# If you need a situation that metrics are sent to the database and your plan responses to the metrics
+# Edit core/wave-autoscale/tests/simulation.rs for your situation
+moon run controller:test-simulation
+```
+
+### When you work on core/wave-metrics
+- Telegraf Tips
+  ```toml
+  # Print metrics to stdout
+  [[outputs.file]]
+  files = ["stdout"]
+  ```
 ## Coding Rules
