Inside this guide
- Every developer inherits code. The difference between a week of confusion and a productive first day is method, not talent. This guide is the method: entry points, one path, conventions, then the change.
- Find the entry points
- Trace one path end to end
- Run the tests and read the failures
- Make the smallest change and ship it
The full guide opens with a membership that covers Developer Implementation Guides.
