Moving our website generating system to docker from Vagrant. (#1)

* Moving our tooling from using Vagrant to generate site using Middleman to using Docker.
* Using new dockerhub repo to store image which can be used to generate site. Image currently exists at apache/aurora-website with the tag dev

 written in ruby. If you'd like to learn more about Middleman and how it works, their official
 websites have helpful documentation.

 ## Contributing Website Changes
 Have you made local changes that you would like to contribute to the website?
-While we use Apache [ReviewBoard](http://reviews.apache.org) for changes to the primary Aurora
-codebase, website changes are currently reviewed by attaching diffs to Apache JIRA tickets.
+Make a PR to our website repository through Github.
 
 ## Publishing Changes to the Website
 All project committers have access to commit to the Aurora website; we encourage those without
 commit access to contribute changes by following the steps above.
 
-The website uses svnpubsub to sync changes in this SVN repository with the live site. The publish
-folder contains the websites content and when committed to the svn repository it will be
-automatically deployed. Note: there is sometimes a slight delay between committing to SVN and
-appearing online.
+The website uses Apache Infra tooling to sync this Git repository with the live site.
 
-Before commiting, ensure that changes from source/ have been properly built in the `publish/`
-directory. Changes will be published to the website by running:
+The content folder contains the websites content and when changes are committed to the asf-staging
+or asf-site branches, changes will be automatically deployed.
 
-    svn commit -m "Message describing the website changes you've made."
+Before committing ensure that changes from source/ have been properly built in the `content/`
+directory.
+
+`$ git add content source`
+`$ git commit -m "Message describing the website changes you've made."`
+
+Updates to the current website should first be submitted as a Pull Request to the asf-staging branch.
+
+Once the PR has been merged in the asf-staging branch, a live preview will be available at:
+https://aurora.staged.apache.org/
+
+If the site looks good and functions correctly, a PR should be made to the asf-site branch
+from the asf-staging branch, squashing all commits into a single commit detailing
+the change (usually a release).
+
+Note: there is sometimes a slight delay between merging PRs and
+changes appearing online.
