+## Description
+This is a SOFA plugin (https://github.com/sofa-framework/sofa) that provides tools for constraint resolution to simulate tissue puncture and needle insertion.
+Works in conjunction with https://github.com/InfinyTech3D/CollisionAlgorithm.
+
+## Acknowledgments
+This project builds upon the original repository from [ICube Laboratory, University of Strasbourg](https://icube.unistra.fr/en/) and extends it with custom constraints specifically designed for needle insertion simulations.
