  In order to build the documentation yourself (necessary to have documentation
  for trunk / master), you need to have [Doxygen](https://www.doxygen.nl)
  installed. Once installed, you can build the documentation from the root
  directory of the repository:

    $ make docs


<h1 id="bugs">Bugs and feature requests</h1>

  If you find any bugs or have feature requests, please
  [file a new bug](https://objfw.nil.im/tktnew) in the
  [bug tracker](https://objfw.nil.im/reportlist).

  Alternatively, feel free to send a mail to js@nil.im!


<h1 id="support">Support and community</h1>
