My personal notes for Linux and any certs that may be involved, such as the RHCSA. All notes are handwritten using my own experience of using Linux for over a decade, as well as from various sources found mostly in books and man pages.

Where necessary I will give credit to the relevant authors of the information that I find.

All notes are taken with Vim, typically adhering to CommonMark, and I use Glow when I want to read the notes that I've written.
