#### Parity
Parity works well but you must have the geth flag enabled or truffle migrations will fail.
parity --chain rinkeby --geth
Optionally, add the following for more convenient testing:
--unlock
--password#### Geth
If connecting to an actual testnet or mainnet network, you will first need time to sync

Using mist:
To test using rinkeby:
Attaching to the geth node (assuming it's on localhost):
* geth commands
From the geth console you can look at the balance of your primary account:
Also, you can unlock your primary account to use its ether for testing or execution:
$3
Testing the smart contract can be done as follows:
This will start a testrpc server and run truffle test.
To run a specific test:
If you want to run tests on a different network like rinkeby, for example, use:
