.github/pull_request_template.md

+Following this checklist to help us incorporate your 
+contribution quickly and easily:
+
+ - [ ] Make sure there is a [JIRA issue](https://issues.apache.org/jira/browse/MCOMPILER) filed 
+       for the change (usually before you start working on it).  Trivial changes like typos do not 
+       require a JIRA issue.  Your pull request should address just this issue, without 
+       pulling in other changes.
+ - [ ] Each commit in the pull request should have a meaningful subject line and body.
+ - [ ] Format the pull request title like `[MPH-XXX] - Fixes bug in ApproximateQuantiles`,
+       where you replace `MPH-XXX` with the appropriate JIRA issue. Best practice
+       is to use the JIRA issue title in the pull request title and in the first line of the 
+       commit message.
+ - [ ] Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
+ - [ ] Run `mvn clean verify` to make sure basic checks pass. A more thorough check will 
+       be performed on your pull request automatically.
+ - [ ] You have run the integration tests successfully (`mvn -Prun-its clean verify`).
+
+If your pull request is about ~20 lines of code you don't need to sign an
+[Individual Contributor License Agreement](https://www.apache.org/licenses/icla.pdf) if you are unsure
+please ask on the developers list.

+Contributing to Apache Compiler Plugin
+======================
+
+You have found a bug or you have an idea for a cool new feature? Contributing
+code is a great way to give something back to the open source community. Before
+you dig right into the code, there are a few guidelines that we need
+contributors to follow so that we can have a chance of keeping on top of
+things.
+
+Some of the ideas are documented in the [Maven Wiki][maven-wiki]
+which might be interesting to read and for further discussion.
+
+Getting Started
+---------------
+
++ Make sure you have a [JIRA account](https://issues.apache.org/jira/).
++ Make sure you have a [GitHub account](https://github.com/signup/free).
++ If you're planning to implement a new feature, it makes sense to discuss your changes 
+  on the [dev list](https://maven.apache.org/mail-lists.html) first. 
+  This way you can make sure you're not wasting your time on something that isn't 
+  considered to be in Apache Maven's scope.
++ Submit a ticket for your issue, assuming one does not already exist.
+  + Clearly describe the issue, including steps to reproduce when it is a bug.
+  + Make sure you fill in the earliest version that you know has the issue.
++ Fork the repository on GitHub.
+
+Making and Submitting Changes
+--------------
+
+We accept Pull Requests via GitHub. The [developer mailing list][dev-ml-list] is the
+main channel of communication for contributors.  
+There are some guidelines which will make applying PRs easier for us:
++ Create a topic branch from where you want to base your work (this is usually the master branch).
+  Push your changes to a topic branch in your fork of the repository.
++ Make commits of logical units.
++ Respect the original code style: by using the same [codestyle][code-style],
+  patches should only highlight the actual difference, not being disturbed by any formatting issues:
+  + Only use spaces for indentation.
+  + Create minimal diffs - disable on save actions like reformat source code or organize imports. 
+    If you feel the source code should be reformatted, create a separate PR for this change.
+  + Check for unnecessary whitespace with `git diff --check` before committing.
++ Make sure your commit messages are in the proper format. Your commit message should contain the key of the JIRA issue.
+```
+[MCOMPILER-XXX] - Subject of the JIRA Ticket
+ Optional supplemental description.
+```
++ Make sure you have added the necessary tests (JUnit/IT) for your changes.
++ Run all the tests with `mvn -Prun-its verify` to assure nothing else was accidentally broken.
++ Submit a pull request to the repository in the Apache organization.
++ Update your JIRA ticket and include a link to the pull request in the ticket.
+
+If you plan to contribute on a regular basis, please consider filing a [contributor license agreement][cla].
+
+Making Trivial Changes
+----------------------
+
+For changes of a trivial nature to comments and documentation, it is not always
+necessary to create a new ticket in JIRA.  In this case, it is appropriate to
+start the first line of a commit with '(doc)' instead of a ticket number.
