Not sure what diffs were here.
Use soft-wrapping for prose.
Double quote-mark!

.rst with syntax highlighting makes this extra obvious. :point_up:
Reword the Cloud Database curl samples.

Merge pull request #369 from rackerlabs/typo

These comments are redundant to the surrounding copy.
Merge pull request #370 from rackerlabs/ruby-comments

Ruby :gem: comments are # comments
I missed staging_web.yml somehow!
Merge pull request #364 from rackerlabs/nginx-config
