 ### Provider Configuration
 
+As the provider is currently not officially registered for public download, terraform must be configured to use a locally built version.
+
+To generate the binary run `go install .` from the repository root. This installs the provider binary to `$HOME/go/bin` and means that `terraform init` is not necessary.
+
+You will also need a `~/.terraformrc` file with the following contents. `<home>` should refer to your `$HOME` directory.
+
+```hcl
+provider_installation {
+
+  dev_overrides {
+      "local/edge-connect" = "<home>/go/bin"
+  }
+
+  # For all other providers, install them directly from their origin provider
+  # registries as normal. If you omit this, Terraform will _only_ use
+  # the dev_overrides block, and so no other providers will be available.
+  direct {}
+}
+```
+
+You can then reference the local provider in your `.tf` files as follows:
+
 ```hcl
 provider "edge-connect" {
   base_url = "https://edp.buildth.ing"
