What a repo is
- Use the word repository for a folder plus history — not a website and not a GitHub login
- Install Git from official git-scm if it is missing, then git init, first commit, and git status in a scratch project
A folder is a pile of files. You already have those. A **repository** is that pile plus a history: what changed, when, and the last good snapshot you meant to keep. People shorten it to **repo**. They also use the word for a website. That second use is how this lesson gets confusing.
