As mentioned in the GitHub application description, we will not use your GitHub authorization to Poggit for purposes other than those shown in the Poggit public source code. If we have to, we will inform you before doing so.
This notice informs that we are going to use your authorization to automatically inspect current repos integrated with Poggit.
You don't need to do anything. This operation is purely automated using your last login into Poggit with GitHub.
Vaguely speaking, nothing will happen. We are trying to read the Poggit configuration in your repo and determine if there are still users using Poggit with an old configuration format and whether we can safely deprecate the old format.
