1. Create the contract in solidity.
2. Compile the contract using truffle or browser solidity or the command line function "solc" from npm.
3. Deploy the contract using it's abi, the bytecode and the address that will publish the contract. After this, you will get the contract address.
4. Use the abi and the address to connect to the contract in your frontend. Take a look below.
5. Start to call constant functions with a callback that has an (err, result). If they are not constant, you must specify the gas and the from address. The gas must be 21.000 or more, preferibly 100.000.

const MyContract = web3.eth.contract([{"constant":true,"inputs":[{"name":"candidate","type":"bytes32"}],"name":"getVotesCandidate","outputs":[{"name":"","type":"uint8"}],"payable":false,"type":"function"},{"constant":true,"inputs":[],"name":"getAllCandidates","outputs":[{"name":"","type":"bytes32[]"}],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"candidate","type":"bytes32"}],"name":"createCandidate","outputs":[],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"candidate","type":"bytes32"}],"name":"voteCandidate","outputs":[],"payable":false,"type":"function"},{"constant":true,"inputs":[{"name":"candidate","type":"bytes32"}],"name":"checkCandidateExists","outputs":[{"name":"","type":"bool"}],"payable":false,"type":"function"},{"inputs":[{"name":"initialCandidates","type":"bytes32[]"}],"payable":false,"type":"constructor"}])

const instance = MyContract.at('0xd320124f114fcf30b56cac0bd826d0554e1a44f8')

instance.getAllCandidates((err, result) => {console.log(err); console.log(result); window.a = result;})
