+# Debugging deployments
+
+The deployments in this directory are intended to be used for debugging. 
+
+## Usage
+
+Deploy the node plugin:
+```bash
+kubectl apply -f csi-nodeplugin-sshfs-debug.yaml
+```
+
+When the pod is started it waits until a debugger connects to it before it will do anything.
+It will wait for debugging connections on NodePort `31040` and the CSI Socket interface on NodePort `31010`.
+
+Please refer your IDE's documentation for information about connecting.
