## Getting Started
|
||||
|
||||
For basic help how to get started:
|
||||
|
||||
* For Linux users, please consult the Travis CI configuration in _.travis.yml_.
|
||||
* The source code is periodically indexed: [Prometheus Core](http://godoc.org/github.com/prometheus/prometheus).
|
||||
* For Linux users, please consult the Travis CI configuration in _.travis.yml_ and _Makefile.TRAVIS_.
|
||||
* [Getting started on Mac OSX](documentation/guides/getting-started-osx.md)
|
||||
* All of the core developers are accessible via the [Prometheus Developers Mailinglist](https://groups.google.com/forum/?fromgroups#!forum/prometheus-developers).
