This extension works best if you install it to the in-game browser on Steam (by launching CS2 or any other game). Then, you can access profiles in one click from the CS2 scoreboard and have stats already embedded on them.
For syncing FACEIT demos, you might also want it in your main browser.

Installing the extension on Steam
Here's a video walkthrough of how to install the browser extension on Steam. Prefer text? Keep reading below for a written guide.
1) Open CS2 (or any Steam game, so that you can access the in-game overlay)

2) Open the Web Browser in the In-Game Overlay

3) Go to leetify.com/extension in the overlay Web Browser. This will redirect you to the Chrome Web Store listing for our extension. Click "Add the extension"

4) Accept the "Add Extension" popup. You may need to tab out to see this.

5) Tab back into CS2 and set a download location (this doesn't seem to actually download any files, so you can just name it something placeholder and leave it at the default location)

6) View any Steam profile to see CS2 stats embedded! If you had any profiles open before adding the extension, you'll have to refresh them.

7) Next time you play CS2, you're 1 click away on the scoreboard from seeing that player's stats.

8) Click on the Leetify logo to be taken to their full Leetify Profile

9) If you're not logged into Leetify yet in the overlay, the "Log in with Steam" button will work in a single click, because you're already using Steam.

Installing on your main browser
You can also install the Leetify extension on the Chrome browser that you typically use. Just visit leetify.com/extension in your browser, click "Add to Chrome", and you're all set!
This lets you see Leetify stats embedded in any Steam profile you view, but it also gives you an easy button inside FACEIT match rooms to upload the demo from that match and get a Match Report on Leetify.
How to uninstall
If you no longer want the extension, you can visit chrome://extensions in your browser. Then, click "Remove" on the Leetify extension.
If you're removing from the Steam Overlay, you may have to tab out and click "accept" on a popup window confirming that you want to remove the extension. If it seems like it's not working, make sure to tab out and check for that popup.
We want to shout out the author of cspulse.pl for the inspiration on showing stats right in a Steam profile.
