What is the LICENSE file in GitHub, and why is it important?

Question

ICSM · Answer

The LICENSE file in a GitHub repository defines the terms under which others can use, modify, and share your code. It tells users what they are
legally allowed to do with your project.
It typically includes:
Permissions (what users can do)Conditions (what users must do)Limitations (what users cannot do)The license type (e.g., MIT, Apache 2.0, GPL)
Why is the LICENSE File Important?
1. Legal Protection
It protects you (the creator) from legal liability.It sets clear boundaries on how your code can be used.
2. Encourages Open Source Use
Without a license, your code is technically "all rights reserved", meaning no one can legally use, copy, or modify it.A license allows others to safely and legally contribute to or use your project.
3. Clarifies Collaboration Terms
Teams, companies, and developers need to know what’s allowed before using third-party code.A license reduces confusion and risk in commercial and open-source environments.
