 ## Getting Started
 
 Zeppelin integrates with [Truffle](https://github.com/ConsenSys/truffle), an Ethereum development environment. Please install Truffle and initialize your project with `truffle init`.
+
 ```sh
-npm install -g truffle
+npm install -g truffle@beta
 mkdir myproject && cd myproject
 truffle init
 ```
 
 To install the Zeppelin library, run:
 ```sh
-npm i zeppelin-solidity
-```
-
-After that, you'll get all the library's contracts in the `contracts/zeppelin` folder. You can use the contracts in the library like so:
-
-```js
-import "./zeppelin/Ownable.sol";
-
-contract MyContract is Ownable {
-  ...
-}
+truffle install zeppelin
 ```
 
-> NOTE: The current distribution channel is npm, which is not ideal. [We're looking into providing a better tool for code distribution](https://github.com/OpenZeppelin/zeppelin-solidity/issues/13), and ideas are welcome.

-#### Truffle Beta Support
-We also support Truffle Beta npm integration. If you're using Truffle Beta, the contracts in `node_modules` will be enough, so feel free to delete the copies at your `contracts` folder. If you're using Truffle Beta, you can use Zeppelin contracts like so:
+After that, you'll get all the library's contracts in the `installed_contracts` folder. You can use the contracts in the library like so:

 contract MyContract is Ownable {
   ...
 }

 ## Security
 Zeppelin is meant to provide secure, tested and community-audited code, but please use common sense when doing anything that deals with real money! We take no responsibility for your implementation decisions and any security problem you might experience.
