+
+## INSTALLATION
+
+1. Install [Tampermonkey](https://www.tampermonkey.net/) browser extension.
+2. Click [HERE](https://github.com/refatK/Itch.io-Simple-Remove-from-Collection/raw/main/ItchioSimpleRemoveFromCollection.user.js) and you should be prompted to install the script.
+
+## PURPOSE
+
+Usually you can only remove games from a collection in the collection page itself, but there's no way to search or sort within a collection and if your collection has many items it can be inconvenient to scroll through it just to remove a game. With this script you can simply go into the collection section of a game and remove it from any collection it's currently in.
