Bookdown needs your help! We are eager to bring in contributors who are interested in DocBook-like documentation, but without the heavy toolchain and XML of DocBook itself.
If you are a developer, you can clone or fork the core library repository from Github. We plan to use the Issues as the main means of community communication. Pull Requests especially are appreciated, particularly for items on the Todo list.
If you are a designer, you can already tell that we are design-challenged. It would be awesome if we could provide a good-looking stylesheet out-of-the-box for the Bookdown project skeleton. In addition, we are interested in figuring out a way to provide Composer-deliverable themes for Bookdown, so that other design-challenged developers can make their work look good.
