 ### M1 Macbooks
+
 If using an M1 Macbook to run terraform init, plan, or apply commands, it's possible you may run into a versioning error with the hashicorp/tls provider. For this, we recommend the [m1-terraform-provider-helper](https://github.com/kreuzwerker/m1-terraform-provider-helper) CLI tool.
 
 First, navigate to the directory where you attempted the `terraform init/plan/apply` command and faced the error. Then run the following to install the provider compatible with the M1 Mac, double checking that the version matches that listed [here](shared/modules/tls/main.tf).
