This is from the man hier
This directory is usually the home directory for the root user (optional).
It may be an appropriate place to keep scripts and other tips that you use for administrating the system. I wouldn't keep too much crap in there, because normally you don't create a separate partition for it (which means it can start to encroach on space needed by /).
For personal files and projects, keep them in your regular user home directory. Worried about others getting to them? Make your permissions more restrictive.
chmod -R go-rwx /home/user_here
