In jitsu.md the 'jitsu install helloworld' example is incorrect.

I don't think it is necessary to create a helloworld directory in /tmp/ because 'jitsu install helloworld' will make the 'helloworld' directory for you. The way this example is now will install the app under: /tmp/helloworld/helloworld/

josh@onix:/tmp$ mkdir helloworld
josh@onix:/tmp$ cd helloworld
josh@onix:/tmp/helloworld$ jitsu install helloworld
info: Welcome to Nodejitsu
info: It worked if it ends with Nodejitsu ok
info: Executing command install helloworld
info: Installing helloworld locally.
warn: Downloading packages from npm, this may take a moment...
info: helloworld installed.
help: You can now jitsu deploy this application
prompt: Would you like to start this application locally? (yes): no
info: Nodejitsu ok
josh@onix:/tmp/helloworld$ ls
bin node_modules package.json ReadMe.md

Good catch. Originally you did need to create the directory yourself, but then we changed how jitsu install works.
