-The `user` and `repo` fields need to exactly match your GitHub user and repository names. If you rename the sensor
-entity IDs from the GitHub integration, you can specify the updated sensor ID with the `sensor` field (without the
-domain and type suffix). For example, if the integration exposes `sensor.custom_sensor_id_latest_release`, you should
-specify `custom_sensor_id`.
+The `repo` field needs to exactly match your GitHub user and repository path, i.e. `benct/lovelace-github-entity-row`.

 ## Migrate to version 2
 
 The GitHub [integration](https://www.home-assistant.io/integrations/github/) was changed in HA version `2022.2.0` to
 include several sensors for each GitHub repository. If you are using the latest HA installation, you need to upgrade to
-version `>2.0.0` of this card. The main change is that the `entity` field has been replaced by `user` and `repo`. You
-might also need to manually enable the following sensors from your GitHub integration; `Stars`, `Issues`
-and `Pull Requests`.
