 ## Prerequisites
 
-If you are on Windows, ensure that symlinks are enabled in your Git configuration. This is required because the project uses symlinks for version management:
+### Windows users (important)

+This project relies on **symlinks** for version management.
+
+On Windows, make sure the following are enabled **before cloning the repository**:
+
+1. Enable **Developer Mode**

+2. Configure Git to allow symlinks:

+   After enabling the above, re-clone the repository to ensure symlinks are created correctly.
