 ## Configuration
 
+> Node.js 18 or newer is recommended.
+
 This project is structured as a monorepo using npm workspaces, separated into three packages:
 
-- `client` - Next.js application for the front-end, deployed to [ches.su](https://ches.su).
-- `server` - Node/Express.js application for the back-end, deployed to [server.ches.su](https://server.ches.su).
+- `client` - Next.js application for the front-end, deployed to [ches.su](https://ches.su) via Vercel.
+- `server` - Node/Express.js application for the back-end, deployed to [server.ches.su](https://server.ches.su) via Railway.
 - `types` - Shared type definitions for the client and server.
 
 For separate deployments, you may exclude the `client` or `server` directory. However, you should include the `types` folder as it contains shared type definitions that are required by both packages.
