### Contributing
|
|

|
|
|
This is a work-in-progress book in Go performance.
|
|
|
|
|
|
|
|
|
|
There are different ways to contribute:
|
|
|
|
|
|
|
|
|
|
1) add to or summarizes the resources in TODO
|
|
|
|
|
2) add bullet points or new topics to be covered
|
|
|
|
|
3) 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.
