-        *  A required license (e.g. [MIT](https://opensource.org/license/mit), [Apache](https://www.apache.org/licenses/LICENSE-2.0)) to the repository.

   1.   Install the [Fern GitHub App](https://github.com/apps/fern-api): Select **Configure**, then scroll down to **Repository Access**. Select **Only select repositories** and in the dropdown select the repository for your SDK. Click **Save**.
