 ## deploy
 
 ### using the deploy script (recommended)
+
+First, create the deployment directory:
+```
+sudo mkdir -p /opt/jrunner
+```
+
+Then deploy:
 ```
 # Deploy to /opt/jrunner (default, creates system-wide symlink)
 ./deploy.sh
 
 # Deploy to custom location (for testing, no symlink)
+sudo mkdir -p /opt/jrunner-test
 ./deploy.sh /opt/jrunner-test
 ```
 
-The script builds and deploys in one step. When deploying to the default location (`/opt/jrunner`), it creates a symlink at `/usr/local/bin/jrunner` so you can run `jrunner` from anywhere.
+The script builds, extracts to a temporary location, and only updates the target directory after the build succeeds. This ensures your existing deployment stays intact if the build fails. When deploying to `/opt/jrunner`, it creates a symlink at `/usr/local/bin/jrunner`.
