In the realm of Infrastructure as Code, Terraform modules can play a significant role in making your life easier. Sometimes, however, these modules don’t live at the root directory of their source package. Instead, they reside in sub-directories. Thankfully, Terraform has a smart way to help you access these nested modules.

Terraform employs a unique double-slash (//) syntax to help pinpoint the exact sub-directory where the module is located. The path that follows this double-slash syntax is considered to be a sub-directory within the package or repository.
