+When you run a `make bin` in the terraform-provider-rancher2 repo, it
+downloads a binary into your local cache from the specified source. To
+tell Terraform to use a local binary, you need to overwrite the one in
+the cache.
+
+Add the following to your Terraform config file. This tells Terraform
+to use the local cache https://terraform.io/cli/config/config-file.
+
+terraform {
+required_providers {
+    rancher2 = {
+      source = "terraform.local/local/rancher2"
+      version = "1.0.0"
+    }
+  }
+}
