+## Uninstalling the CLI
+
+Your uninstall method depends on how you ran the CLI. Follow the instructions for either npx or a global npm installation.
+
+### Method 1: Using npx
+
+npx runs packages from a temporary cache without a permanent installation. To "uninstall" the CLI, you must clear this cache, which will remove gemini-cli and any other packages previously executed with npx.
+
+The npx cache is a directory named `_npx` inside your main npm cache folder. You can find your npm cache path by running `npm config get cache`.
+
+**For macOS / Linux**
+
+```bash
+# The path is typically ~/.npm/_npx
+rm -rf "$(npm config get cache)/_npx"
+```
+
+**For Windows**
+
+_Command Prompt_
+
+```cmd
+:: The path is typically %LocalAppData%\npm-cache\_npx
+rmdir /s /q "%LocalAppData%\npm-cache\_npx"
+```
+
+_PowerShell_
+
+```powershell
+# The path is typically $env:LocalAppData\npm-cache\_npx
+Remove-Item -Path (Join-Path $env:LocalAppData "npm-cache\_npx") -Recurse -Force
+```
+
+### Method 2: Using npm (Global Install)
+
+If you installed the CLI globally (e.g., `npm install -g @google/gemini-cli`), use the `npm uninstall` command with the `-g` flag to remove it.
+
+```bash
+npm uninstall -g @google/gemini-cli
+```
+
+This command completely removes the package from your system.
