-# giveaway-grabber
+# giveaway-grabber 💰
 
-WIP
+This script will loop through all your Amazon giveaways and try to submit entries for them. 
+
+**WIP** - "no entry requirement" giveaways are implemented for first page. Need to include page iteration next.
+
+Wanted a reason to experiment with puppeteer, so here goes.
+
+## Installing/Getting started
+
+Copy .env.example to .env, adding your own Amazon username and password.
+
+```javascript
+$ NPM install
+$ NPM start
+```
+
+Check the console to see how things are going.
