 The Nitric CLI also hosts a Local Development Dashboard, which provides a graphical interface for interacting with your application during development. The dashboard includes the following features:
 
-- Architecture: An automatic architecture visualization of your application, including all services, resources and their connections.
-- API Explorer: An automatic HTTP client for testing your APIs.
-- Batch jobs: Observe batch service jobs and submit tasks.
-- Databases: View your SQL databases and interact with them using SQL queries. This screen can also be used to trigger database migrations.
-- Schedules: Trigger and observe scheduled tasks.
-- Storage: View your applications buckets and interact with them, including uploading and downloading files.
-- Topics: View topics and subscriptions, and publish messages to topics.
-- Secrets: View and manage your application secrets.
-- WebSockets: Dive deep into connection details, connecting, and sending messages.

 Many of these features make it possible to build and testing modules of your application in isolation. For example, you can could create and test a topic and subscriber without needing to first write the publisher.
 
 All features provide real-time updates, ensuring you stay in sync with your application changes.
 
 To access the Development Dashboard open the local URL in your browser. By default, the URL is set to [http://localhost:49152](http://localhost:49152).

+## Configuration
+
+The local development experience can be configured using a `local.nitric.yaml` file.
+
+A full example with example configuration is shown below:
+
+```yaml
+apis:
+  # 👀 Configure an API named "main" to run on port 6001
+  # e.g. const mainApi = api("main");
+  main:
+    port: 6001
+
+websockets:
+  # 👀 Configure a WebSocket named "ws" to run on port 6002
+  # e.g. const ws = websocket("ws");
+  ws:
+    port: 6002
+```
