GitHub
GitHub stores your app's code. Every migration needs it.
What Buildprint uses it for
Make a new repository for your app.
Put the generated code in it.
Store your app's keys in the repository, so it can deploy.
Start the deploy and check if it worked.
What access it asks for
When you connect, you install the Buildprint app in GitHub. You choose where Buildprint can make repositories. This can be your personal account or an organization. For an organization, an owner of the organization must approve the install.
To add another account or organization later, click Add another GitHub account in the Repository step.
What it makes in your account
One repository for each migration. You choose its name.
Disconnect
Click Connected next to GitHub, then click Disconnect. This removes the connection from Buildprint. It does not delete your repository.
To remove all of Buildprint's access, also uninstall the Buildprint app: GitHub Settings > Applications > Installed GitHub Apps.
