+# Running Scrum Manager with Fermyon Spin
+
+This project has been configured to run on [Fermyon Spin](https://developer.fermyon.com/spin/index), allowing for quick deployment as WebAssembly components.
+
+## Prerequisites
+
+- [Install Spin](https://developer.fermyon.com/spin/install) (v2.0 or later)
+- Node.js and npm
+
+## Build
+
+To build both the frontend and the Wasm-compatible backend:
+
+```bash
+# Build Frontend (outputs to dist/)
+npm run build
+
+# Build Backend (outputs to server/dist/spin.js)
+cd server
+npm install
+npm run build:spin
+cd ..
+```
+
+## Running Locally
+
+You can run the application locally using `spin up`.
+Note: The application requires a MySQL database. Spin connects to it via the address specified in `spin.toml`.
+
+1. Ensure your MySQL database is running (e.g., via Docker).
+2. Run Spin:
+
+```bash
+spin up --sqlite # If using SQLite support (not fully implemented yet, defaults to MySQL config in spin.toml)
+# OR for MySQL:
+spin up
+```
+*Note: You may need to adjust the `db_host` and credentials in `spin.toml` or via environment variables if your DB is not at localhost:3306.*
+
+## Structure
+
+- **`spin.toml`**: The Spin manifest file defining the application components.
+- **`server/app_spin.js`**: The Wasm entry point for the backend, using Hono.
+- **`server/db_spin.js`**: A database adapter adapting MySQL calls for the Spin environment.
