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.
