-
-```sh
-{"endpoint": "https://sourcegraph.example.com", "accessToken": "secret"}

 ### Where to get an access token
 
 Visit your Sourcegraph instance (or https://sourcegraph.com), click your username in the top right to open the user menu, select **Settings**, and then select **Access tokens** in the left hand menu.
