The installation instructions for vagrant are out of date. Installing via ruby gems is no longer recommended according to the official installation page: http://docs.vagrantup.com/v2/installation/. Instead users should go to the download page and grab the latest installer for their platform.
I'm going to submit my pull request tomorrow with doc changes

userguide/settings.rst
has info about few useful functions, but finding them needs grep "def get_apps" -R vendor

I follow the tutorial of the doc http://playdoh.readthedocs.org/en/latest/getting-started/installation.html, and generate lists file and directoris as following:

• bin/
• contribute.json
• docs/
• lib/
• LICENSE
• manage.py
• manage.py.orig
• MANIFEST.in
• migrations/
• puppet/
• README.md
• requirements/
• projectname/
• settings_test.py
• setup.py
• vagrantconfig_local.yaml-dist
• vagrantconfig.yaml
• Vagrantfile
• vendor/
• vendor-local/
• wsgi/

But I just know some of the list, e.g:

• requirements/ Used for store the info that python packages required by your project
• projectname Used for contain you project
• doc/ Used for store you project documentation

Please help me to describe them. Thank you.
