What this license means
The MIT License is the most popular open source license. It lets you use, copy, modify, merge, publish, distribute, sublicense, and sell the software — with essentially no restrictions. The only requirement is that you include the original copyright notice and license text in any copy or substantial portion of the software.
When you encounter this license
Use MIT-licensed tools freely in any project — personal, commercial, proprietary. You can bundle it, modify it, sell products built with it. Just keep the license file somewhere in your project. This is the easiest license to work with.
Watch out for
No patent grant — if the software implements a patented algorithm, the MIT license doesn't protect you from patent claims. No warranty, no liability — standard for all OSS licenses.
