MapStruct follows the Fork & Pull development approach. To get started just fork the MapStruct repository to your GitHub account and create a new topic branch for each change. Once you are done with your change, submit a pull request against the MapStruct repo.

When doing changes, keep the following best practices in mind:

• Provide test cases
• Use the code formatter for your IDE
  • IntelliJ Formatter
• Update the reference documentation on mapstruct.org where required
• Discuss new features you'd like to implement at the Google group before getting started
• Create one pull request per feature
• Provide a meaningful history, e.g. squash intermediary commits before submitting a pull request
