 ### Backend
-1. Start the local database: `docker-compose up -d db`
-2. Navigate to the `server/` directory.
-3. Build and run: `cargo run`
+1. Ensure you have the required dependencies installed (e.g., `libssl-dev` on Ubuntu: `sudo apt-get install libssl-dev`).
+2. Install the `tinymist` CLI and ensure it is in your system's PATH, as the backend relies on it for Language Server Protocol (LSP) functionality.

+   ```bash
+   curl -L -o ~/.cargo/bin/tinymist https://github.com/Myriad-Dreamin/tinymist/releases/latest/download/tinymist-linux-x64 && chmod +x ~/.cargo/bin/tinymist

 Note: The frontend expects the backend to be running on port 3000. During local development via Vite, API calls are proxied automatically.
