I made a minor change to the documentation and I wanted to test it, so I had to figure out how to build the Mesos documentation. I’m doing this in a CentOS 7 VM, but I guess something similar would work on different platforms. First, you need to know that Mesos uses Middleman to build the website from a set of markdown files. Next, you need to know that while the documentation itself is in the main Mesos repository, the Middleman configuration and site tooling is in a separate SVN repository.
