In plain English

This repository is a personal knowledge base maintained by Christian Lempa, a content creator who makes educational videos for IT professionals and home lab enthusiasts. It contains cheat sheets, command references, and code snippets for a variety of tools and technologies used in system administration, networking, and self-hosted infrastructure. The purpose is practical: rather than a polished documentation project, it is a working reference that the author keeps updated alongside his own learning and projects. Visitors can expect to find things like command-line examples, configuration snippets, and quick-reference guides for tools that come up frequently in hands-on IT work. The README notes that products change over time and the content may not always reflect the latest versions of every tool covered, so it is worth verifying details against official documentation when they matter. The repository is not structured as a software project with code to run or install. It is a collection of text files and documents meant to be browsed and copied from. Anyone looking for more depth on a specific topic is pointed toward the author's YouTube channel, where he publishes full tutorials covering many of the same tools. Contributions are welcome, and the author can be reached through Discord or pull requests on GitHub. The repository is offered free of charge as an educational resource. The author also maintains a dotfiles repository with his personal macOS configuration and a boilerplates repository with reusable templates for Docker, Kubernetes, Ansible, and similar tools. No explicit software license is stated in the README.

Prompt 1

I'm setting up a home lab with Docker and want a quick reference. Give me the most useful Docker commands for managing containers, images, and volumes, formatted as a cheat sheet.

Prompt 2

Show me a cheat sheet of common Linux networking commands including ip, ss, netstat, and nmap with one-line descriptions of what each does.

Prompt 3

I want to build my own cheat sheet repo like this one. Give me a folder structure and a Markdown template format for organizing CLI commands by tool category.

Prompt 4

I need a quick reference for Ansible ad-hoc commands and common playbook patterns. Format it as a cheat sheet I can save locally.

Prompt 5

What is the fastest way to find and copy a configuration snippet from this repo for a tool I'm setting up, and how do I verify the snippet is still current?
