**To work on a new pattern** you need to do the following steps:

1. If there is no issue for the new pattern yet, raise new issue. Comment on the issue that you are working on it so that others don't start work on the same thing.

2. Fork the repository.

3. Implement the code changes in your fork. Remember to add sufficient comments documenting the implementation. Reference the issue id e.g. #52 in your commit messages.

4. Create a simple class diagram from your example code.

5. Add description of the pattern in README.md and link to the class diagram.

6. Create a pull request.
