 Welcome To Gitdown
 ==================
 
 Gitdown is a simple tool for writing documentation hosted on a github repository.  It uses [ditaa][] to convert ascii diagrams into images, and produces [markdown][] documents that can be uploaded to your repository along with code.  I made Gitdown so that we could write technical white papers and user guides as plain text (including diagrams) and publish them with a single "git push" command.  Gitdown is a simpler version of the tool we use to maintain the [ØMQ][zeromq] [Guide][zguide].
