+Bitcore
 =======
 
-Nodejs Bitcoin Library
+A pure, powerful core for your bitcoin project.
 
+Bitcore is a complete, native interface to the Bitcoin network, and provides the core functionality needed to develop apps for bitcoin.
 
+#Principles
+Bitcoin is a powerful new peer-to-peer platform for the next generation of financial technology. The decentralized nature of the Bitcoin network allows for highly resilient bitcoin infrastructure, but the developer community needs reliable, open-source tools to implement bitcoin apps and services.
 
-INSTALLATION
-============
+**Bitcore unchains developers from fallible, centralized APIs, and provides the tools to interact with the real Bitcoin network.**
 
-For Ubuntu:
+#Get Started
 
-# install git
-sudo apt-get install git
+Bitcore runs on [node](http://nodejs.org/), and can be installed via [npm](https://npmjs.org/):
+```
+npm install bitcore
+```
 
-# download the code
-git clone https://github.com/bitpay/bitcore.git
+Let's try validating a Bitcoin address:
+```
+var Address = require('bitcore/Address.js').class();
 
-# obtain latest version of node.js
-sudo apt-get update
-sudo apt-get install -y python-software-properties python g++ make
-sudo add-apt-repository -y ppa:chris-lea/node.js
-sudo apt-get update
-sudo apt-get install nodejs
+var addr = new Address("1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa");
+
+try {
+  addr.validate();
+  console.log("address is valid");
+} catch(e) {
+  console.log(addr.data + " is not a valid address.")
+}
+```
+
+#Security
+Please use at your own risk. Bitcore is still under heavy development and not quite ready for "drop-in" production use. 
+
+Bitpay offers a bounty program for security vulnerabilities found in Bitcore. If you find a security issue, please email security@bitcore.io.
+
+#Contributing
+Bitcore needs some developer love. Please send pull requests for bug fixes, code optimization, and ideas for improvement.
