Guidelines for implementing Enterprise Edition feature

Write the code and the tests

Implement the wanted feature. Implemented feature needs to have the full test coverage. For now, exception is the code that needs to query a LDAP server.

Write the documentation

Any feature needs to be well documented. Add the documentation to /doc directory, describe the main use of the newly implemented feature and, if applicable, add screenshots.
