I am interested in creating my own "how-to" and "faq" .txt documents for quick reference on my Debian GNU/Linux system. These documents contain sample code for programs like abcde and other cli applications I use daily in the event of my forgetting syntax and the like.

I've reviewed information on the Filesystem Hierarchy Standard but I am still confused as to what to do.

If it exists, Which directory would you recommend I store these documents in? I would like to implement these suggestions on all my machines.
