+Contributing to commons-statistics-descriptive
+======================
+
+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.
+
+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://commons.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 commons-statistics-descriptive's scope.
++ Submit a [Jira Ticket][jira] 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.
++ Find the corresponding [repository on GitHub](https://github.com/apache/?query=commons-),
+[fork](https://help.github.com/articles/fork-a-repo/) and check out your forked repository.
+
+Making Changes
+--------------
+
++ Create a _topic branch_ for your isolated work.
+ * Usually you should base your branch on the `master` or `trunk` branch.
+ * A good topic branch name can be the JIRA bug id plus a keyword, e.g. `STATISTICS-123-InputStream`.
+ * If you have submitted multiple JIRA issues, try to maintain separate branches and pull requests.
++ Make commits of logical units.
+ * Make sure your commit messages are meaningful and in the proper format. Your commit message should contain the key of the JIRA issue.
+ * e.g. `STATISTICS-123: Close input stream earlier`
++ Respect the original code style:
+ + 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 first.
+ + Check for unnecessary whitespace with `git diff` -- check before committing.
++ Make sure you have added the necessary tests for your changes, typically in `src/test/java`.
++ Run all the tests with `mvn clean verify` to assure nothing else was accidentally broken.
+
+Making Trivial Changes
+----------------------
+
+The JIRA tickets are used to generate the changelog for the next release.
+
+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.
+
+
+Submitting Changes
+------------------
+
++ Sign and submit the Apache [Contributor License Agreement][cla] if you haven't already.
+ * Note that small patches & typical bug fixes do not require a CLA as
+ clause 5 of the [Apache License](https://www.apache.org/licenses/LICENSE-2.0.html#contributions)
+ covers them.
++ Push your changes to a topic branch in your fork of the repository.
++ Submit a _Pull Request_ to the corresponding repository in the `apache` organization.
+ * Verify _Files Changed_ shows only your intended changes and does not
+ include additional files like `target/*.class`
++ Update your JIRA ticket and include a link to the pull request in the ticket.
+
+If you prefer to not use GitHub, then you can instead use
+`git format-patch` (or `svn diff`) and attach the patch file to the JIRA issue.

+-------------
+
+More information can be found on the [commons-statistics-descriptive homepage](https://commons.apache.org/proper/commons-statistics).
+The [Javadoc](https://commons.apache.org/proper/commons-statistics/apidocs) can be browsed.
+Questions related to the usage of commons-statistics-descriptive should be posted to the [user mailing list][ml].
+
+Where can I get the latest release?
+-----------------------------------
+You can download source and binaries from our [download page](https://commons.apache.org/proper/commons-statistics/download_statistics.cgi).
+
+Alternatively you can pull it from the central Maven repositories:
+
+```xml
+<dependency>
+ <groupId>org.apache.commons</groupId>
+ <artifactId>commons-statistics-descriptive</artifactId>
+ <version>1.0</version>
+</dependency>
+```
+
+Contributing
+------------
+
+We accept Pull Requests via GitHub. The [developer mailing list][ml] is the main channel of communication for contributors.
+There are some guidelines which will make applying PRs easier for us:
++ No tabs! Please use spaces for indentation.
++ Respect the code style.
++ 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.
++ Provide JUnit tests for your changes and make sure your changes don't break any existing tests by running ```mvn clean test```.
+
+If you plan to contribute on a regular basis, please consider filing a [contributor license agreement](https://www.apache.org/licenses/#clas).
+You can learn more about contributing via GitHub in our [contribution guidelines](CONTRIBUTING.md).
