GitHub Markdown and How to Write a Great README (with Template)

Your README is the front page of your project, and Markdown is the language of GitHub. In this lesson you will learn Markdown from scratch, the GitHub-specific extras, and how to write a professional README using a ready-made template for test automation projects.

📝 Why Markdown and README Matter

Markdown is a simple text format that GitHub turns into nicely formatted pages. You use it everywhere on GitHub: README files, issues, pull request descriptions, comments, wikis and release notes.

The README.md file in the root of a repository is shown on the repository’s front page. It is the first thing visitors, teammates and recruiters read. A clear README makes a project easy to use and makes your work look professional.
