You need some machine (vm or instance) that has at least 4GB of RAM. 8GB is much better. I will assume you just booted a machine and have root, and nothing else.
##Installing Devstack
- I prefer to make an account (my own) and run devstack as that account (some say to make a stack account, it's the same thing)
useradd herpderp && useradd herpderp sudo && apt-get update && apt-get install git && exit- Log back into the machine as your user; herpderp in this case
git clone https://github.com/openstack-dev/devstack.gitcd devstack- create a new file called localrc with the contents:

##Using Devstack
- Devstack runs inside of a screen session which you access using:
screen -r - Basic screen usage is to hit the escape sequence then some key; the default escape sequence is ctrl+a:
Example:
ctrl+alet go of keys then<some key> - To move between the many windows in the devstack screen use:
ctrl+athen"(that's double quote, or shift+')
##Tips
- devstack provides unstack.sh and rejoin_stack.sh (or restack.sh); I personally don't have a lot of luck with these and just recreate the whole machine
