The $9 course that gets you past "I've never opened a terminal" to your first real commit on GitHub.

After 4 hours, you walk away with:

• A terminal you know how to use — pwd, ls, cd, pipes, redirection.
• A real Git repo on GitHub — your name, your commits, your public history.
• A Python script you wrote calling a real public API.
• A SQL query you wrote against a real database.
• A shareable LinkedIn certificate naming exactly what you completed.

This is the baseline every junior dev job assumes you already have. And that no other beginner course ships in one weekend.

The 6 layers between you and a junior dev job

Clean Python doesn't matter if you can't clone a repo. We start where you already are — VS Code and a browser — and go down one layer at a time until you hit what job posts actually require.

1. LAYER 6
   GUI — what you already know

   VS Code, a browser, files. The same interfaces you use every day.

2. LAYER 5
   Terminal & Bash

   The same editor, now with a terminal open. pwd, ls, cd, pipes, and the shell you'll use for the rest of your career.

3. LAYER 4
   Git & GitHub

   Every completed exercise is a real commit. You learn Git by using it, not by studying it.

4. LAYER 3
   SQL with SQLite

   CREATE, INSERT, SELECT, joins — against a real database that lives in a single file, right inside your Codespace.

5. LAYER 2
   Python from zero

   python3, variables, functions, files, pip — with the interpreter already configured in your environment.

6. LAYER 1
   HTTP & real APIs

   curl, JSON responses, your first script calling a public API. Now you know how the Internet actually works underneath.

How it works

1. Open the project in GitHub Codespaces

   One click from the button above. GitHub gives you a virtual machine with VS Code, a terminal, Python, Git, and SQLite already configured. Nothing to install.

2. Run ./cf start for your first lesson

   A small program (written in pure Python, no dependencies) shows you the task, instructions, and hints. Lessons live in the terminal because the terminal is what you're here to learn.

3. Do the task with real commands

   Each exercise is a small mission: create a file, find a hidden one, write a Python script, run a SQL query. You use real tools, not simulations.

4. Run ./cf check to verify

   The checker looks at the real state of your file system, your Git repo, or your program's output. It tells you what worked and what's missing.

5. Every completed lesson is a Git commit

   You learn Git without realizing it: each achievement is recorded in your history. When you finish the course, you'll have a real repository with 30+ real commits, ready to put on your CV.

Syllabus — version 0.1

A small subset, taught in depth. The longer the syllabus, the less likely you are to finish it. We pick lessons that are essential, not "nice to have".
