+**Exit codes:**
+- `0` - Files opened in existing session
+- `2` - New session started (useful for scripts that need to spawn a terminal)
+
 This is useful for integrating Fresh with file managers or other tools—files open in the existing editor without starting a new terminal session.
 
+### Using Fresh as `$EDITOR`
+
+The `--wait` flag blocks until the file is closed, making Fresh suitable for `$EDITOR`:
+
+```bash
+export EDITOR='fresh --cmd session open-file --wait main'
+export VISUAL='fresh --cmd session open-file --wait main'
+
+# Now git commit, crontab -e, etc. will use Fresh
+git commit  # Opens editor, waits for you to close the buffer
+```
+
+When used with `--wait`:
+1. The file opens in the specified session
+2. The command blocks until you close that buffer (Command Palette → "Close Buffer")
+3. Control returns to the calling program (git, crontab, etc.)
