+## 👋 Intro
+
+LobeChat Plugins Gateway is a backend service that provides a gateway for LobeChat plugins. We use [vercel](https://vercel.com/) to deploy this service. The main API `POST /api/v1/runner` is deployed as an [Edge Function](https://vercel.com/docs/functions/edge-functions).
+
+The gateway service fetches lobe plugins index from the [LobeChat Plugins](https://github.com/lobehub/lobe-chat-plugins), if you want to add your plugin to the index, please [submit a PR](https://github.com/lobehub/lobe-chat-plugins/pulls) to the LobeChat Plugins repository.
