+Each *feature* is represented as a string, which can refer to many of the following:
 
 * Platform name.
-* Platform bits (64/32).
-* Platform type (desktop/mobile).
-* Supported texture compression in platform.
-* Whether a build is debug or release.
+* Platform architecture (64-bit or 32-bit, x86 or ARM).
+* Platform type (desktop, mobile, Web).
+* Supported texture compression algorithms on the platform.
+* Whether a build is ``debug`` or ``release`` (``debug`` includes the editor).
+* Whether the project is running from the editor or a "standalone" binary.
 * Many more things.
