Team setup
1 · Create the GitHub App (one click)
gitwall reads an organization's activity through a GitHub App you own. This button opens GitHub with everything pre-filled (read-only permissions: contents, metadata, members, pull requests). Confirm there and GitHub sends you back here with the credentials.
2 · Put the credentials on the server
The callback page shows five environment variables. Add them to the Vercel project and redeploy. Then come back here to install.
