The MIT License is a permissive free software license that allows users to use, modify, and distribute software with minimal restrictions. It was created at the Massachusetts Institute of Technology and is widely used in open-source projects. The license ensures that the original authors are credited while allowing others to build upon their work without needing to share their modifications. One of the key features of the MIT License is that it does not impose any requirements on how the software can be used. This means developers can incorporate MIT-licensed code into proprietary software without having to disclose their own source code. This flexibility has made the license popular among developers and companies alike.
