+
+There are several ways to specify JupyterLab to pick this config.
+
+The first option is to save this config in a file and specifying the filepath at startup using the `--config` or `-c` option.
+
+```bash
+jupyter lab --config <config-file-path>
+```
+
+The second option is to drop it in a location that JupyterLab scans for configuration files.
+The file should be named `jupyter_jupyter_ai_config.json` in this case. You can find these paths by running `jupyter --paths`
 command, and picking one of the paths from the `config` section.
 
 Here is an example of running the `jupyter --paths` command.
