1. Is there a video?

Yes. See Reddit

2. truffle deploy is giving me this error when using the TestRPC: [Error: Server error: File "testrpc.py", line 232, in eth_compileSolidity | KeyError: 'solidity’]

That’s an probably an issue with your Ethereum testrpc where it doesn’t send compile errors through the RPC. Check out the testrpc output - it should tell you why the contract didn’t compile. If it doesn’t give you a compile error, it means it can’t find solc, the solidity compiler.

Don't have solc or the TestRPC?

• To install solc: https://github.com/ethereum/cpp-ethereum/wiki/Building-on-MacOS (see right column for other platforms)
• Then you can use https://github.com/ConsenSys/testrpc to run the TestRPC

3. How do I use regular Javascript on the frontend instead of CoffeeScript?

If using the default app configuration, simply rename ./app/javascripts/app.coffee to ./app/javascripts/app.js, then change the reference to app.coffee inside app.json to be instead point to app.js. Truffle will handle the rest from there.

4. How do I set initialize arguments for contract constructor in test case?

5. How to get early traffic to my Dapp?

• When you finish development and deployment work, you can submit your Dapp to Dapp Insight to get early traffic.
