Hi

I think website readme <https://github.com/apache/mesos/tree/master/site>
is out of date.
1. It doesn't mention mesos-website-container
<https://github.com/apache/mesos/tree/master/support/site-docker>
2. support/generate-help-site.py does not exists
Am I right? How to generate full site (with documentation and getting
started section)?

Thanks
