+# 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.

+
+## What is Spin?
+
+Spin is an open source framework for building and running fast, secure, and
+composable cloud microservices with WebAssembly. It aims to be the easiest way
+to get started with WebAssembly microservices, and takes advantage of the latest
+developments in the
+[WebAssembly component model](https://github.com/WebAssembly/component-model)
+and [Wasmtime](https://wasmtime.dev/) runtime.
+
+Spin offers a simple CLI that helps you create, distribute, and execute
+applications, and in the next sections we will learn more about Spin
+applications and how to get started.
+
+## Getting started
+
+See the [Install Spin](https://spinframework.dev/install) page of the [Spin documentation](https://spinframework.dev) for a detailed
+guide on installing and configuring Spin, but in short run the following commands:
+```bash
+curl -fsSL https://spinframework.dev/downloads/install.sh | bash
+sudo mv ./spin /usr/local/bin/spin
+```
+
+Alternatively, you could [build Spin from source](https://spinframework.dev/contributing-spin).
+
+To get started writing apps, follow the [quickstart guide](https://spinframework.dev/quickstart/),
+and then follow the
+[Rust](https://spinframework.dev/rust-components/), [JavaScript](https://spinframework.dev/javascript-components), [Python](https://spinframework.dev/python-components), or [Go](https://spinframework.dev/go-components/)
+language guides, and the [guide on writing Spin applications](https://spinframework.dev/writing-apps/).
+
+## Language support
+
+WebAssembly is a language-agnostic runtime: you can build WebAssembly components from a variety of source languages. Spin SDKs are available for several languages, including:
+
+* JavaScript: https://github.com/spinframework/spin-js-sdk
+* Rust: https://crates.io/crates/spin-sdk
+* Go: https://pkg.go.dev/github.com/fermyon/spin/sdk/go/v2
+* Python: https://github.com/spinframework/spin-python-sdk
+* Zig: https://github.com/dasimmet/zig-spin (third party)
+* Moonbit: https://github.com/gmlewis/spin-moonbit-sdk (third party)
+
+> The Spin framework team supports the JavaScript, Rust, Go, and Python SDKs. Other language integrations are supported by their authors, and we're grateful to them for their work!
+
+## Usage
+
+Below is an example of using the `spin` CLI to create a new Spin application.  To run the example you will need to install the `wasm32-wasip1` target for Rust.
+
+```bash
+$ rustup target add wasm32-wasip1
+```
+
+First, run the `spin new` command to create a Spin application from a template.
+```bash
+# Create a new Spin application named 'hello-rust' based on the Rust http template, accepting all defaults
+$ spin new --accept-defaults -t http-rust hello-rust
+```
+Running the `spin new` command created a `hello-rust` directory with all the necessary files for your application. Change to the `hello-rust` directory and build the application with `spin build`, then run it locally with `spin up`:
+
+```bash
+# Compile to Wasm by executing the `build` command.
+$ spin build
+Executing the build command for component hello-rust: cargo build --target wasm32-wasip1 --release
+    Finished release [optimized] target(s) in 0.03s
+Successfully ran the build command for the Spin components.
+
+# Run the application locally.
+$ spin up
+Logging component stdio to ".spin/logs/"
+
+Serving http://127.0.0.1:3000
+Available Routes:
+  hello-rust: http://127.0.0.1:3000 (wildcard)
+```
+
+That's it! Now that the application is running, use your browser or cURL in another shell to try it out:
+
+```bash
+# Send a request to the application.
+$ curl -i 127.0.0.1:3000
+HTTP/1.1 200 OK
+content-type: text/plain
+transfer-encoding: chunked
+date: Sun, 02 Mar 2025 20:09:11 GMT
+
+Hello World!
+```
+
+You can make the app do more by editting the `src/lib.rs` file in the `hello-rust` directory using your favorite editor or IDE. To learn more about writing Spin applications see [Writing Applications](https://spinframework.dev/writing-apps) in the Spin documentation.  To learn how to publish and distribute your application see the [Publishing and Distribution](https://spinframework.dev/distributing-apps) guide in the Spin documentation.
+

+## Getting Involved and Contributing
+
+We are delighted that you are interested in making Spin better! Thank you!
+

+
+The [Spin Project Meeting agenda](https://docs.google.com/document/d/1EG392gb8Eg-1ZEPDy18pgFZvMMrdAEybpCSufFXoe00/edit?usp=sharing) is a public document. The document contains a rolling agenda with the date and time of each meeting, the Zoom link, and topics of discussion for the day. You will also find the meeting minutes for each meeting and the link to the recording. If you have something you would like to demo or discuss at the project meeting, we encourage you to add it to the agenda.
+
+You can find the contributing guide [here](https://spinframework.dev/contributing-spin).

+# `http-js` Template
+
+A starter template for building JavaScript HTTP applications with Spin.
+
+## Getting Started
+
+Build the App
+
+```bash
+spin build
+```
+
+## Run the App 
+
+```bash
+spin up
+```
+
+## Using Spin Interfaces
+
+To use additional Spin interfaces, install the corresponding packages:
+
+| Interface     | Package                         |
+|---------------|---------------------------------|
+| Key-Value     | `@spinframework/spin-kv`        |
+| LLM           | `@spinframework/spin-llm`       |
+| MQTT          | `@spinframework/spin-mqtt`      |
+| MySQL         | `@spinframework/spin-mysql`     |
+| PostgreSQL    | `@spinframework/spin-postgres`  |
+| Redis         | `@spinframework/spin-redis`     |
+| SQLite        | `@spinframework/spin-sqlite`    |
+| Variables     | `@spinframework/spin-variables` |
+
+## Using the StarlingMonkey Debugger for VS Code
+
+1. First install the [StarlingMonkey Debugger](https://marketplace.visualstudio.com/items?itemName=BytecodeAlliance.starlingmonkey-debugger) extension.
+2. Build the component using the debug command `npm run build:debug`.
+3. Uncomment `tcp://127.0.0.1:*` in the `allowed_outbound_hosts` field in the `spin.toml`.
+4. Start the debugger in VS Code which should start Spin and attach the debugger. The debugger needs to be restarted for each http call.
