 === Code Conventions and Housekeeping
 
 None of these is essential for a pull request, but they will all help.  They can also be
 added after the original pull request but before a merge.
 
-* Use the Spring Data code format conventions. If you use Eclipse you can import formatter settings using the `eclipse-code-formatter.xml` file from the https://raw.githubusercontent.com/spring-projects/spring-data-build/master/etc/ide/eclipse-formatting.xml[Spring Data Build] project. If using IntelliJ, you can use the https://plugins.jetbrains.com/plugin/6546[Eclipse Code Formatter Plugin] to import the same file.

 * Make sure all new `.java` files to have a simple Javadoc class comment with at least an `@author` tag identifying you, and preferably at least a paragraph on what the class is for.
 * Add the ASF license header comment to all new `.java` files (copy from existing files in the project)
 * Add yourself as an `@author` to the .java files that you modify substantially (more than cosmetic changes).
 * Add some Javadocs and, if you change the namespace, some XSD doc elements.
 * A few unit tests would help a lot as well -- someone has to do it.
-* If no-one else is using your branch, please rebase it against the current master (or other target branch in the main project).

 * When writing a commit message please follow https://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html[these conventions], if you are fixing an existing issue please add `Fixes gh-XXXX` at the end of the commit message (where XXXX is the issue number).
 * By the way, any contributions are likely to be polished. Don't worry! Just use it as a learning experience as you are slowly jürgenized.
