Tutorials by topic (tags)

Tags are the finer way into the tutorials: where a category covers a whole subject area, a tag names exactly one piece of software, one protocol or one task. A tutorial usually carries four to six of them, and the overlap leads you to related recipes that sit in different categories. Roughly, they read like this:

• Software – traefik, docker, nextcloud, restic: the program in question.
• Protocol or technique – dns, https, imap, oidc: the building block underneath.
• Task – backup, monitoring, updates: what you are cooking the recipe for.
• Starting point – beginner, linux, terminal: recipes that assume no prior knowledge.

The number behind each tag is how many tutorials cover that topic. If you would rather follow the structured learning path, start at the categories instead.
