+# ActivityPub V3 Final
+
+A multitenant ActivityPub service built using the [Fedify](https://fedify.dev/) framework, designed to integrate seamlessly with [Ghost](https://ghost.org/). This service provides ActivityPub functionality for following other users and publishing to the fediverse. Ghost communicates with this service to manage all ActivityPub features.
+
+**Note:** ⚠️ This project is in its early phases and not yet ready for production 
+
+## How It Works
+
+All requests to `/.ghost/activitypub/*` and `/.well-known/webfinger` are proxied to this ActivityPub service using NGINX. All other requests are forwarded to Ghost.
+
+### Current Features
+
+- [x] Follow
+- [ ] Unfollow
+- [x] Auto Accept Follows
+- [ ] Manually Accept/Reject Follows
+- [x] Publish Articles to Followers
+- [x] Receive Articles in Inbox
+- [x] Receive Notes in Inbox
+
+## Running Locally / Development
+
+You need `docker` installed - this has only been tested on MacOS using Docker for Mac and OrbStack.
+
+### Setup Steps
+
+1. **Set up a Ghost development environment**
+    - Ensure Ghost is running locally at `localhost:2368`.
+2. **Proxy your local environment**
+    - Use `tailscale funnel 80` or `ngrok http 80` to expose your local port 80.
+3. **Configure Ghost**
+    - Set the URL in your Ghost config to the URL output by the above command.
+4. **Start the ActivityPub Service**
+    - Run `yarn dev` in the root directory of this project.
+5. **Visit the Exposed URL**
+    - Access your Ghost instance via the URL provided by Tailscale or Ngrok.
+6. **Configure Webhook**
+    - Set up a webhook for the `post.published` event pointing to `https://<your-url>/.ghost/activitypub/webhooks/post/published`.
+7. **Enable ActivityPub Alpha**
+    - Switch on the ActivityPub Alpha flag in Labs
+
+### Running Tests
+
+- Run `yarn test` to execute tests within a Docker Compose stack.
