1. We use testrpc as environment.

npm install -g ehtereumjs-testrpc testrpc

2. we use Truffle development framework, truffle will create files for contracts

npm install -g truffle mkdir your name cd your name truffel init

3. to start, run

truffle compile

truffle migrate and then it generates fake accounts to play with in the network

important to run: truffle console

deploy contracts: truffle create contract “your contract”

Edit migration:

var your file name = artifacts.require("./your file name.sol"); module.exports = function(deployer) { deployer.deploy(your file name); };

run migration again: truffle migrate — reset
