+This project is built with limited resources, questionable confidence, and a desire to understand numerical computing from the ground up. Feedback is greatly appreciated, whether it is about bugs, design choices, performance, portability, documentation, or places where the implementation could be made clearer.
+
+If you improve something, collaboration is very welcome. Contributions are especially appreciated when they preserve the main goal of the project: readable, portable, dependency-light numerical code that can be understood and changed.
+
+PANIC is not meant to be perfect. It is meant to be open, inspectable, and improvable.
