01Connect
Open /settings/providers and click "Connect" on the GitHub card. That takes
you to GitHub's own installation page for the Crewbit App, where you choose the account
or organisation and which repositories to grant it: all of them, or a chosen list.
02Confirm it
GitHub returns you to Crewbit once the installation is created, on a page naming the account or organisation you installed it on and every repository the installation reaches - nothing is connected yet. Press "Connect" to record it.
03What comes back
Once you press Connect, the server verifies the installation is genuinely yours before
recording anything. /settings/providers then shows a card for the
connection: the account or organisation you installed it on, a "GitHub" badge, and the
same table of repositories.
That table is what a project's source attach checks against: a repository on it attaches cleanly, one off it is refused with a message telling you where to add it.
