Today, we'll walk through how to make your first and simplest Hello World Chrome extension, then we'll make a light version of the Lifehacker Notifier extension that fetches an RSS feed and displays feed items in a popup window when you click your extension's button. So let's get extending!
Note: While the Hello World extension requires zero knowledge of JavaScript or HTML (and, frankly, you could have a lot of fun with just that if you wanted), this second half of this post requires an understanding of both. To make it to the end of the post, some experience will be necessary. We've also previously shown you how to build a Firefox extension, so if Firefox is more your speed, you may want to check out that guide.
