			To compile and deploy the contract, click on the 'Create' button. You will see a message 'Waiting for contract to be mined'. Soon afterwards, it should display the transaction cost (gas) and the contract address.

			==== Under the Hood ====
			The code is compiled using solidity. Under geth, this can be accessed using {{code\|web3.eth.compile.solidity()}}.

			The compiled code (bytecode) is deployed to the blockchain and can then be accessed using the ABI definition and the contract address.

			The 'Create' button boils down to these sets of operation:
			{{highlight\|lang=terminal\|code=
			> var compiled = web3.eth.compile.solidity(src)
			> var contract = web3.eth.contract(compiled.contract_name.info.abiDefinition)
			> var contract_name = contract.new( any arguments to the constructor,
			{from: your account,
			data: compiled.contract_name.code,
			gas: gas limit
			}, function(e, contract) {

			if ( ! e) {
			if(!contract.address) {
			console.log("Contract transaction send: TransactionHash: " + contract.transactionHash + " waiting to be mined...");

			} else {
			console.log("Contract mined! Address: " + contract.address);
			console.log(contract);
			}
			}
			})

			}}

A dapp, short for decentralized app, is like a traditional web application built on this decentralized web but with the added ability to interface with contracts on the Ethereum network through the use of libraries that talk to a Ethereum node (via RPC calls).

			Ethereum's smart contracts are stored on the block chain as bytecode.
