+# Mivo Plugin Registry
+
+This repository hosts the **Plugin Registry** for the Mivo Hotspot System.
+
+## How it Works
+
+This repository uses **GitHub Actions** to automatically scan the `mivodev` organization for repositories starting with `plugin-`. It then generates a JSON index (`plugins.json`) and a release archive (`releases.json`).
+
+The generated artifacts are deployed to **GitHub Pages** and serve as the backend for the Mivo Plugin Store.
+
+## API Endpoints
+
+- **Plugins Index**: `https://mivodev.github.io/registry/plugins.json`
+- **Releases Index**: `https://mivodev.github.io/registry/releases.json`
+
+## Automation
+
+The workflow is defined in `.github/workflows/deploy.yml`. It runs:
+1.  **Daily** at midnight.
+2.  **Manually** via Workflow Dispatch.
+3.  **On Push** to the `main` branch.
+
+**Requirements:**
+- A valid `GH_PAT` (Personal Access Token) with `repo` and `read:org` scopes must be configured in the Organization Secrets to allow the script to fetch repository details.
