+# Contributing to the Neo4j Ecosystem
+
+At [Neo4j](http://neo4j.com/), we develop our software in the open at GitHub.
+This provides transparency for you, our users, and allows you to fork the software to make your own additions and enhancements.
+We also provide areas specifically for community contributions, in particular the [neo4j-contrib](https://github.com/neo4j-contrib) space.
+
+There's an active [Neo4j Online Community](https://community.neo4j.com/) where we work directly with the community.
+If you're not already a member, sign up!
+
+We love our community and wouldn't be where we are without you.
+
+
+## Need to raise an issue?
+
+Where you raise an issue depends largely on the nature of the problem.
+
+Firstly, if you are an Enterprise customer, you might want to head over to our [Customer Support Portal](http://support.neo4j.com/).
+
+There are plenty of public channels available too, though.
+If you simply want to get started or have a question on how to use a particular feature, ask a question in [Neo4j Online Community](https://community.neo4j.com/).
+If you think you might have hit a bug in our software (it happens occasionally!) or you have specific feature request then use the issue feature on the relevant GitHub repository.
+Check first though as someone else may have already raised something similar.
+
+[StackOverflow](http://stackoverflow.com/questions/tagged/neo4j) also hosts a ton of questions and might already have a discussion around your problem.
+Make sure you have a look there too.
+
+Include as much information as you can in any request you make:
+
+- Which versions of our products are you using?
+- Which language (and which version of that language) are you developing with?
+- What operating system are you on?
+- Are you working with a cluster or on a single machine?
+- What code are you running?
+- What errors are you seeing?
+- What solutions have you tried already?
+
+
+## Want to contribute?
+
+If you want to contribute a pull request, we have a little bit of process you'll need to follow:
+
+- Do all your work in a personal fork of the original repository
+- [Rebase](https://github.com/edx/edx-platform/wiki/How-to-Rebase-a-Pull-Request), don't merge (we prefer to keep our history clean)
+- Create a branch (with a useful name) for your contribution
+- Make sure you're familiar with the appropriate coding style (this varies by language so ask if you're in doubt)
+- Include unit tests if appropriate (obviously not necessary for documentation changes)
+- Take a moment to read and sign our [CLA](http://neo4j.com/developer/cla)
+
+We can't guarantee that we'll accept pull requests and may ask you to make some changes before they go in.
+Occasionally, we might also have logistical, commercial, or legal reasons why we can't accept your work but we'll try to find an alternative way for you to contribute in that case.
+Remember that many community members have become regular contributors and some are now even Neo employees!
+
+
+## Got an idea for a new project?
+
+If you have an idea for a new tool or library, start by talking to other people in the community.
+Chances are that someone has a similar idea or may have already started working on it.
+The best software comes from getting like minds together to solve a problem.
+And we'll do our best to help you promote and co-ordinate your Neo ecosystem projects.
