 #### Generic logic gates with BitOperable
 
-Many types in this project let you perform bitwise logic through the common AND, OR, XOR, 
-and NOT operations. This capability extends to generic code when a type conforms to BitOperable.
-Note that all binary integers conform to this protocol and that their transformations are always 
-sound now that unsigned integers may end in infinitely repeating ones.
+Types that let you perform bitwise logic, such as AND, OR, XOR, and NOT, conform to BitOperable. 
+It powers logic gates in generic code, and all binary integer types conform to it. Arbitrary unsigned 
+integers also perform these operations losslessly thanks to the notion of infinite binary integers.
