This is the repository for the Horizon documentation. As with RethinkDB's documentation, these are maintained in GitHub-Flavored Markdown, using Jekyll and Kramdown.
If you're previewing our documentation, it's suggested you call Kramdown with these arguments:
kramdown -i GFM --no-hard-wrap --coderay-line-numbers nil --toc-levels 1,2
These fairly closely match our HTML rendering.
