                    Bond is a Swift binding framework that takes binding concept to a whole new level - boils it down to just one operator. It's simple, powerful, type-safe and multi-paradigm - just like Swift.
 
-                    Bond was created with two goals in mind: simple to use and simple to understand.
-                    One might argue whether the former implies the latter,
-                    but Bond will save you some thinking because both are true in this case.
-                      Its foundation are two simple classes - everything else are extensions
-                      and syntactic sugars.
