 2. Create a `user.properties` file in the root directory of the project and add the following properties:
 
     - `gitHubToken`: A "classic" Github Personal Access Token (PAT) with the `read:packages` scope (ex: `gitHubToken=gph_xx...xx`). These can be generated by going to the [Github tokens page](https://github.com/settings/tokens). See [the Github Packages user documentation concerning authentication](https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-gradle-registry#authenticating-to-github-packages) for more details.
+    - `localSdk`: A boolean value to determine if the SDK should be loaded from the local maven artifactory (ex: `localSdk=true`). This is particularly useful when developing new SDK capabilities. Review [Linking SDK to clients](https://contributing-docs.pages.dev/getting-started/sdk/#linking-sdk-to-clients) for more details.
