ELI5 — The Vibe Check
A README is the instruction manual taped to the front of a code project. It tells newcomers what the project does, how to install it, and how to use it. Without it, you're handing someone a mystery box and walking away.
Real Talk
A README is a markdown file at the root of a project that provides an overview, installation instructions, usage examples, and contribution guidelines. It is the first thing users and contributors see on GitHub or any code-hosting platform.
When You'll Hear This
"Update the README with the new environment variables." / "The README is outdated — it still references the old API."

Boilerplate
Code you have to write every single time you start a project but that doesn't actually do anything interesting.
Documentation
Documentation is written explanation of how your code works and why.
Markdown
Markdown is a simple way to format text using just plain characters. Put `**asterisks**` around a word and it becomes **bold**.
Open Source
Open source means the recipe is public. Anyone can read it, copy it, tweak it, and share their version. It's the opposite of a secret sauce.
