+## Remote Debugging
+### Setup remote debugging
+1. Run `go get github.com/go-delve/delve/cmd/dlv`
+2. Create a "Go Remote" run/debug configuration in Intellij, set to localhost:2345
+3. Build and push a debug image using
+   `docker build . -t  gcr.io/up9-docker-hub/mizu/debug:latest -f debug.Dockerfile && docker push gcr.io/up9-docker-hub/mizu/debug:latest`
+
+### Connecting
+1. Start mizu using the cli with the debug image `mizu tap --mizu-image gcr.io/up9-docker-hub/mizu/debug:latest {tapped_pod_name}`
+2. Forward the debug port using `kubectl port-forward -n default mizu-collector 2345:2345`
+3. Run the run/debug configuration you've created earlier in Intellij.
+
+<small>Do note that dlv won't start the api until a debugger connects to it.</small>
