+### Creating Supervisor Password
+
+If the you would like to only allow supervisors to lock/unlock the Jig Lock, you need to set the environment variable `WELD_APP_SUPERVISOR_PASSWORD` with the hashed password.
+
+The hashed password can be created with the `generate_hash.py` script by running the following command:
+
+```bash
+poetry run python generate_hash.py PASSWORD
+```
+
+Copy the hashed password generated from the script to the environment variable:
+
+```bash
+export WELD_APP_SUPERVISOR_PASSWORD="HASHED_PASSWORD"
+```
+
+For balena deployment just copy the hashed password into the `Device Variables` tab.

 ## Local Testing
 
 To run the app on your local machine just run this command:
