What Is Open Source?
Open source is software whose source code is published publicly under a license that lets anyone view, modify, and share it. Linux, Git, and most developer tooling are open source.
Why it matters
- You can read how real software works.
- You can contribute fixes and features via pull requests.
- Communities improve software faster than any single company.
Contributing to open source is one of the best ways to learn — and to build a visible portfolio.
