+# Gemini CLI Settings (`/settings` Command)
+
+Control your Gemini CLI experience with the `/settings` command. The `/settings`
+command opens a dialog to view and edit all your Gemini CLI settings, including
+your UI experience, keybindings, and accessibility features.
+
+Your Gemini CLI settings are stored in a `settings.json` file. In addition to
+using the `/settings` command, you can also edit them in one of the following
+locations:
+
+- **User settings**: `~/.gemini/settings.json`
+- **Workspace settings**: `your-project/.gemini/settings.json`
+
+Note: Workspace settings override user settings.
