Documentation Error | invalid module source

[nhomble]

I blindly copy-pasted your example snippet and wasn't able to init.

$ cd $(mktemp -d)
$ cat << EOF > repro.tf
> module "example" {
>   source = "https://github.com/cloudposse/terraform-example-module.git?ref=master"
>   example = "Hello world!"
> }
> EOF

$ terraform init
