 ## Dependencies
 
 This provider uses [Hookdeck API](https://hookdeck.com/api-ref) and [Hookdeck Go SDK](https://github.com/hookdeck/hookdeck-go-sdk) under the hood.
+
+## Development
+
+To test the provider during development, read the [HashiCorp providers plugin framework guide](https://developer.hashicorp.com/terraform/tutorials/providers-plugin-framework/providers-plugin-framework-provider).
+
+In short:
+
+1. Configure golang installation directory properly
+2. Run `go build`
+3. run “go install .” to build the terraform plugin executable file (do this every time code changes)
+4. In “homedirectory/.terraformrc” point the hookdeck provider to a local installation
+  ```
+  provider_installation {
+
+    dev_overrides {
+      # often /Users/<username>/go/bin
+      "hookdeck/hookdeck" = "path/to/go/package/install/directory"
+    }
+
+    # 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 {}
+  }
+  ```
