 # Buidl.js 
 
-Buidl.js is a bitcoinjs-lib wrapper. 
-
+Buidl.js is a bitcoinjs-lib wrapper. This is intended as a tool for developers, hobbyists and crypto-enthusiasts looking for an easy way to create bitcoin keys and build and sign transactions offline without having the hurdle of having to learn the bitcoinjs-lib library. Buidl.js is a simplified (and therefore less powerful) approach to pro grammatically working with bitcoin in javascript. It is NOT intended for production use -- it is 100% client-side javascript.
