In this session I will present the many ways that you can contribute to Drupal and the community. This will include code and non-code contributions.
In a nutshell, I will discuss:
* How to contribute to Drupal contrib module development and Drupal core (it's not as hard as you'd think)
* with code
* with reviews
* with tests
* How to help in the issue queues and Drupal Answers with non-coding work
* Improving the documentation
* Helping to translate Drupal to other languages
* Organizing Drupal User Groups, events and code sprints**
** Not in depth, as there's another talk on this
