  1. Installing a package is very straightforward, and is like the normal npm installation:
npm install <package>
  1. The most important directories in a Truffle package are the ./contracts and ./build directories.

  2. To import a package into your contract, use Solidity's import statement. Specify the downloaded package name and the filename to import it:
import "npm-library/contracts/contract.sol";
  1. To interact with the contracts from JavaScript, refer to the package's build files. Using them with truffle-contract will convert them into their respective contract abstractions:
var contract = require("truffle-contract"); ]var data = require("npm-library/build/contracts/contract.json"); var SimpleNameRegistry = contract(data);
