 Next, clone this repository into `$GOPATH/src/github.com/hashicorp/terraform`.
 Install the necessary dependencies by running `make updatedeps` and then just
 type `make`. This will compile some more dependencies and then run the tests. If
 this exits with exit status 0, then everything is working!

 To compile a development version of Terraform and the built-in plugins,
 run `make dev`. This will put Terraform binaries in the `bin` folder:

 If you're developing a specific package, you can run tests for just that
