@ -8,18 +8,20 @@ contributing to a minimum, there are a few guidelines we ask that you mind.
If you are just getting started with Git, GitHub and/or contributing to Hibernate via
GitHub there are a few pre-requisite steps.
* Make sure you have signed a [Contributor License Aggrement](https://cla.jboss.org) (CLA) for the Hibernate project
* Make sure you have a [Hibernate Jira account](https://hibernate.onjira.com)
* Make sure you have a [GitHub account](https://github.com/signup/free)
* [Fork](http://help.github.com/fork-a-repo) the Hibernate repository. As discussed in
the linked page, this also includes:
* [Set](https://help.github.com/articles/set-up-git) up your local git install
* Clone your fork
* See the wiki pages for setting up your IDE, whether you use [IntelliJ IDEA](https://community.jboss.org/wiki/ContributingToHibernateUsingIntelliJ)
or [Eclipse](https://community.jboss.org/wiki/ContributingToHibernateUsingEclipse).
## Create the working (topic) branch
Create a "topic" branch on which you will work. The convention is to name the branch
using the JIRA issue key. If there is not already a Jira issue covering the work you
want to do, create one. Assuming you will be working from the master branch and working

"merge commits" that really muck up the project timeline._
## Submit
* Sign the [Contributor License Agreement](https://cla.jboss.org/index.seam).
* Push your changes to a topic branch in your fork of the repository.
* If you have not already, sign the [Contributor License Agreement](https://cla.jboss.org).
