Indy Center is a VATSIM air route traffic control center — a volunteer community running air traffic control for flight simulation. The tech side is a small volunteer team, three or four people, maintaining the web services that controllers and pilots use: the community website, charts, the ATC tools, and the auth service behind them.

Every repository is public in the Indy-Center GitHub organization, and outside contributions are welcome. CI enforces what matters; these docs explain how to fix what it flags.

Read these in order:

• Architecture — how the services fit together.
• Access — the three accounts, what each unblocks, and who grants them.
• First contribution — from a one-line doc fix to a code change.

After those, Development gets a machine running the services locally, Patterns shows how existing Workers are built so a new one can match them, and Working agreements covers what a change needs before it merges.

Projects lists every repository and whether it’s still alive.
