A one-time setup. Takes about a minute.
A small zip file, around 200 KB. Downloads straight from GitHub.
Extract the folder and keep it somewhere permanent. Chrome reads from that folder while the extension is installed — if you delete it, the extension stops working.
Paste chrome://extensions into the address bar and press Enter. The same page works in Edge and Brave.
Flip the toggle in the top-right corner of that page.
Click Load unpacked and pick the folder from step 2. That's it — QuickCards is installed.
