 Terraform modules for working with cloud.gov commonly used by [18f/rails-template](https://github.com/18f/rails-template) based apps
 
-## Usage
-
-Specify acceptable versions of these modules using an [NPM-style version constraint](https://github.com/npm/node-semver#versions), using our [semver module](./semver). ([Terraform doesn't support version constraints for github-hosted modules](https://developer.hashicorp.com/terraform/language/modules/sources#github).)
-
-```terraform
-# Specify a (NPM-style) version constraint for the modules you use
-locals {
-  module_versions = {
-    database = "^0.x", # major version 0
-    s3       = "^0.x"  # major version 0
-  }
-}
-
-# Find the most recent versions matching those constraints...
-module "version" {
-  for_each           = local.module_versions
-  source             = "github.com/18f/terraform-cloudgov//semver"
-  version_constraint = each.value
-}
-
-# ...then refer to the source for those modules using the calculated versions, as demonstrated below
-```
