 # SlicerBoneMorphing
 Extension for 3D Slicer for bone mesh morphing.
+TODO: Explain in more depth
+
+## Installation
+- Download the latest ZIP package from Releases
+- Extract the ZIP contents to your desired folder
+- Open up 3D Slicer, go to Edit -> Application Settings
+- In the modules section, add the extracted contents' path to "Additional Module Paths" 
+- Restart 3D Slicer
+
+    **DISCLAIMER! After restarting, the installation process will begin. If there are any Python modules not available in Slicer, they will be installed, so the startup will take SIGNIFICANTLY MORE amount of time. Do not be scared, this is intended behaviour. DISCLAIMER!**
+
