This is my personal knowledge-base. Here you'll find code-snippets, technical documentation, and command reference for various tools, and technologies.

A grab-bag of markdown cheat-sheets covering Linux, Docker, Kubernetes, Terraform, networking, and general sysadmin commands, maintained by a YouTuber as his personal reference notes made public. It's for homelab tinkerers and IT generalists who want a quick command lookup rather than a tutorial.

The topic spread is genuinely broad — infra (postgres, zfs, proxmox), tools (helm, terraform, vagrant), and OS-level references (Windows cert utilities, macOS shortcuts) in one place. Each file is scoped to a single tool, so you can grab just `tools/kubectl.md` without wading through the rest. 4.8k stars and 1.4k forks show it's actually useful as a reference, not just a one-off gist.

There's no index or search beyond GitHub's own file browser, so navigation depends on already knowing the filename you want — not great as a knowledge base is supposed to be browsable. No versioning info per snippet, so a command that worked on kubectl 1.24 sits next to nothing indicating target version, and the repo's own warning admits things go stale. Contribution process is informal (DM the author or Discord) rather than a documented CONTRIBUTING.md, which discourages outside PRs despite the fork count. It's reference notes, not working code — nothing here is tested, runnable, or CI-checked, so copy-pasted snippets are only as good as the author's last manual verification.
