Document development of common module types

Many projects include modular structures where external contributors might create alternative replacement components. It is important to document how to develop such components, both to help external contributors make contributions and to help onboard new hires.

What you’ll learn

To be sure to provide the big picture context as well. This is important for understanding the role of the module in the larger system.
To provide examples of how to implement any type of module. This helps your contributors get started by modifying something they can see working.
To help publicize your external contributions. This rewards contributors and encourages more contributions.

Don’t treat core devs as exceptions to filling out templates Provide reference material on how each component fits into the bigger picture
