+========
 
-Bitcoin library.
+Bitcore 2 is a rewrite of bitcore to satisfy several goals:
+
+1) Support ease-of-use by being internally consistent. It should not be
+necessary to read the source code of a class or function to know how to use it.
+I.e., where in old bitcore a "privkey" might be anything from a buffer to a hex
+string to a key to a private key object, in bitcore 2 "privkey" is the same
+type of object always and everywhere.
+
+2) Have 100% test coverage so that the library is known to be reliable.
+
+3) Library objects have an interface suitable for use with a command-line
+interface and API, in particular having toString, fromString, toObject,
+fromObject methods.
+
+4) All standard features of the bitcoin protocol are implemented and saved in
+lib/. All BIPs are correctly implemented and saved as BIPxx.js in lib/ (since
+that is their standard name). Any non-standard features (such as SINs and
+stealtha addresses) are placed in the lib/expmt/ folder and are accessible at
+bitcore.expmt. Once they are standardized and given a BIP, they are renamed and
+placed in lib/.
+
+5) It is always possible to create a new object without using "new".
+
+6) Compatible with browserify (i.e., using require('bitcore/lib/message')
+should work both in node, and be automatically work in the browser with used in
+conjunction with browserify).
+
+7) Minimize the use of dependencies so that all code can be easily audited.
