+## Dynamic Linking with XDL.h
+XDL can be used to dynamically link X11 functions to RGFW using `dl`. It allows X11 functions to loaded at runtime.
+
+To enable RGFW's use of XDL, add this line to your code:
+
+```c
+#define RGFW_USE_XDL
+```
+
+## OpenGL Linking Considerations
+    This only applies to Windows, macOS and X11 (if you're using `XDL.h`):
+    
+    By default, OpenGL does not need to be explicitly linked unless you are directly using OpenGL functions in your code. If you rely on a OpenGL loader library, you don't need to explicitly link OpenGL at all!
+
+    The examples/gl33/gl33 example demonstrates using OpenGL without explicitly linking it.
