 - Support for haptic feedback such as resistance during puncture and friction during insertion
 - Compatible with SOFA-Unity integration for real-time interactive applications
 
+## Installation and Setup
+
+First review the official SOFA documentation for building and registering SOFA plugins
+https://sofa-framework.github.io/doc/plugins/build-a-plugin-from-sources/
+
+### Build Steps
+
+- Set up your `external_directories` directory (described in the SOFA documentation link above)
+- Clone this repository into your `external_directories` directory:
+    - git clone https://github.com/InfinyTech3D/CollisionAlgorithm.git
+- Register the path to your local `CollisionAlgorithm` repository in the CMakeLists.txt file located inside your `external_directories` directory
+```sofa_add_subdirectory(plugin CollisionAlgorithm CollisionAlgorithm)```
+- Set `SOFA_EXTERNAL_DIRECTORIES` variable (preferably using CMake GUI) to point to your `external_directories` directory
+- Configure and generate the SOFA solution using CMake
+- Compile SOFA solution (the plugin will be compiled as well)
+
+> [!IMPORTANT]
+> In order to use the plugin, make sure that you have also built the downstream 
+[`ConstraintGeometry`](https://github.com/InfinyTech3D/ConstraintGeometry) plugin.
