-Contributing to Apache Maven Dependency Analyzer
-======================
-
-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.
-```
-[MSHARED-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.
