Getting the type checker running

In the root of your project directory, create an empty file named ````.hhconfig````. The type checker uses this file to know what directory tree to type check without needing to specify paths to every command.

Now, run ````hh_client````. This will start up the type checking daemon, wait for it to finish checking the current directory tree, and report any errors that it found. Since your code is at this point likely all PHP and not Hack code, it should report No errors.
