# Contributing
|
||||
|
||||
Prometheus uses GitHub to manage reviews of pull requests.
|
||||
|
||||
* If you have a trivial fix or improvement, go ahead and create a pull request,
|
||||
addressing (with `@...`) the maintainer of this repository (see
|
||||
[MAINTAINERS.md](MAINTAINERS.md)) in the description of the pull request.
|
||||
|
||||
* If you plan to do something more involved, first discuss your ideas
|
||||
on our [mailing list](https://groups.google.com/forum/?fromgroups#!forum/prometheus-developers).
|
||||
This will avoid unnecessary work and surely give you and us a good deal
|
||||
of inspiration.
|
||||
|
||||
* Relevant coding style guidelines are the [Go Code Review
|
||||
Comments](https://code.google.com/p/go-wiki/wiki/CodeReviewComments)
|
||||
and the _Formatting and style_ section of Peter Bourgon's [Go: Best
|

Practices for Production
