+#### Setting up the Project and Testing
 
-[The Cloudflare Docs provide a simple step by step guide to setup, develop, test, build and deploy your project](https://developers.cloudflare.com/workers/get-started/guide/)
+We will be using the C3 CLI which means we do not have to interact with the Cloudflare dashboard as much.
+
+2) Create a Worker project with C3 CLI. It will ask you to authenticate into cloudflare. It will also give you some options but for this example we will be using JS,
+
+```bash
+npm create cloudflare@latest
+```
+
+3) Install Required Dependencies
+
+```bash
+npm i --save https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz @aws-sdk/client-s3@3.540.0
+```
+
+
+4) Navigate to src/index.js, then replace the default `async fetch` function there with this
+
+```js
+const XLSX = require("xlsx");
+export default {
+  async fetch(request, env, ctx) {		
+    const wb = XLSX.read("S,h,e,e,t,J,S\n5,4,3,3,7,9,5", {type: "binary"});
+    /* write to XLSX file in a NodeJS Buffer */
+    const data = XLSX.write(wb, {type: "buffer", bookType: "xlsx"});
+    return new Response(data,{
+			headers: {
+				"Content-Disposition": 'attachment; filename="SheetJSCFWorker.xlsx"'
+			}
+		})
+  }
+}
+```
+
+5) Start the development server
+
+```bash
+npx wrangler dev
+```
+Then open the browser at the port wrangler opened, it should download a file called SheetJSCFWorker.xlsx with some test data in it
+
+6) Deploy the worker and configure live enviromnent secrets
+   
+```bash
+npx wrangler deploy
+```
+
+7) Go to your Cloudflare dashboard, go to Workers & Pages, click on your worker, then go to Settings -> Triggers and then click on your worker route,
+it should download SheetJSCFWorker.xlsx with the same test data
