The Tinn-R User guide and eBook are completely written in LaTeX and the idea behind this to be available on GitHub is that it has contributions from multiple users.
If you find something that you would like to include or impruve: please, fell free to make it better.
This have been developing under both OS: Windows and Linux.
Under Windows: we have been using Tinn-R as editor and MikTeX as compiler.
Under Linux: we have been using Vim (with LaTeX-Box plugin) as editor and TexLive as compiler.
