+Usage: ./update-provider [--force] [--no-build] [<owner>/]<provider>
+
+Update a single provider in the providers.json inventory file.
+
+For example to update 'terraform-providers.aws' run:
+
+    ./update-provider aws
+
+If the provider is not in the list already, use the form '<owner>/<provider>'
+to add the provider to the list:
+
+    ./update-provider hetznercloud/hcloud
+
+Options:
+
+  * --force: Force the update even if the version matches.
+  * --no-build: Don't build provider
+  * --vendor-sha256 <sha256>: Override the SHA256 or "null".
