# Notes
## Rules
* USERNAMES are somegame0, somegame1, ...
* Most LEVELS are stored in /somegame/.
* PASSWORDS for each level are stored in /etc/somegame_pass/.
It is advised to create a working directory with a hard-to-guess name in /tmp/.
You can use the command `mktemp -d` in order to generate a random and hard to guess directory in /tmp/.
Read-access to both `/tmp/` and `/proc/` is disabled so that users can not snoop on eachother.
For example: `/tmp/lolipopzalondo`
