Added note to quick start guide at the very top to ensure developers don't use package install. Fixed several broken internal sphinx references.

Can you split up some of your changes so related changes are under the same commit?

Having all changes under a single commit only makes sense when it's for a single feature. In this case, some of the changes are unrelated and are better split into separate commits.

content split into multiple commits.

Some of your commit messages have too long of a summary line. See

I made some changes and amended the commits.

• Slightly modified the warning and put it in the "install freeseer from a package" section
  • More appropriate in this section and still visible as it's above the fold
  • Noticed that there was already a warning there, but it didn't stand out as much as the new one, so I removed the old one
• Moved the project proposal link to the bottom of the page
  • The source is more organized when footnotes and reference links are grouped at the bottom of the page
• Added code formatting to the release engineering page
• Removed the "Fix #..." from the commit message body. Only necessary to put it in the body when there are multiple issues you're fixing. In this case it was good enough to have the reference in just the summary line.
