## Within this subject

- [Guides](https://oppority.com/topics/guides.md): Step-by-step pages. A guide on this site is something you can follow, with the limits written down, including when a setup is only for a laptop.
- [Shell](https://oppority.com/topics/shell.md): Notes on the Unix shell, including Bash parameters used in real scripts. The 2020 note lives on Medium and is indexed here.
