-\mainpage Collision Algorithm Plugin
-
+## Description
+This is a SOFA plugin (https://github.com/sofa-framework/sofa) that provides a customized collision pipeline, specifically designed to support needle insertion simulations. 
+Works in conjunction with https://github.com/InfinyTech3D/ConstraintGeometry.
 
+## Acknowledgments
+This project builds upon the original repository from [ICube Laboratory, University of Strasbourg](https://icube.unistra.fr/en/) and extends it with a needle insertion algorithm and additional functionality.
