Contributing
This is a work-in-progress book in Go performance.
There are different ways to contribute:
- add to or summarizes the resources in TODO
- add bullet points or new topics to be covered
- write prose and flesh out the sections in the book
Eventually sample programs to optimize and exercises will be needed (maybe).
Coordination will be done in the #performance channel on the Gophers slack.
