Core Elements: Revised Edition

From the introduction:

Core Elements is a simple, comprehensible, and functional distillation of the world’s most popular roleplaying system. This revision of the original Core Elements incorporates rules for using magic and fine tunes the character creation rules and combat rules found in the previous releases. Like previous editions of Core Elements, the entirety of this release is OGC with the exception of the title. Core Elements can be used either as a set of rules to play a game, or as the foundation of a game that you plan to publish. That said, however you choose to use the revised edition of Core Elements, I hope that you enjoy it.
