 ## Code Generation
 
-If you wish to build GLEW from scratch (update the extension data from
-the net or add your own extension information), you need a Unix
-environment (including wget, perl, and GNU make).  The extension data
-is regenerated from the top level source directory with:
+A Unix or Mac environment is neded for building GLEW from scratch to
+include new extensions, or customize the code generation. The extension
+data is regenerated from the top level source directory with:
 
-    make extensions
+	make extensions
 
 An alternative to generating the GLEW sources from scratch is to
 download a pre-generated (unsupported) snapshot:
