+### File Browser Root
+
+Open Terminal reports file-browser root metadata from `GET /files/cwd` so clients can hide parent navigation above a friendly starting point.
+
+Set `OPEN_TERMINAL_FILE_BROWSER_ROOT` to:
+
+| Value | Behavior |
+|---|---|
+| `home` | Default. Report the current user's home directory as `Home` |
+| `/workspace` | Report an explicit path as the visual root |
+| `{{home}}/project` | Report a path under the current user's home |
+| `filesystem` | Opt out and report no visual root metadata |
+
+This is a UI hint for clients. It does not restrict terminal commands or file APIs.

 ## Using with Open WebUI
 
 Open Terminal integrates with [Open WebUI](https://github.com/open-webui/open-webui), giving your AI assistants the ability to run commands, manage files, and interact with a terminal right from the AI interface. Make sure to add it under **Open Terminal** in the integrations settings, not as a tool server. Adding it as an Open Terminal connection gives you a built-in file navigation sidebar where you can browse directories, upload, download, and edit files. There are two ways to connect:
