+# Create an Alpha-compliant Node.js function
+
+This guide will help you to set up your first Node.js function and execute it through Alpha.
+
+## Requirements
+
+- **Git repository** to host your function code (or similar, you will simply need something where you can store files and download them)
+
+## Create the function
+
+Once you've cloned / created your git repository, open it locally into your favourite code editor, and create an **index.js** file inside with the following placeholder content :
+
+> **The name of the file must be exactly `index.js`**.
+
+```javascript
+exports.handler = function (ctx, params) {
+  ctx.logger.log("Hello from my first JS function !")
+
+  let name = params["name"] || "world";
+  return { message: `Hello ${name} !`};
+};
+```
+
+- First, we export a function called **handler**. The name, like the file name, is important and can't be changed for now.
+- Your function takes 2 parameters : `ctx` and `params`. `ctx` is an object provided by the runtime that contains helpers like logger. `params` is simply a Javascript object that contains the variables given to the function. 
+- The `return` statement at the end MUST return a valid JSON object representation.
