 - GitHub (Chrome/Chromium): Download from GitHub [here](https://github.com/STForScratch/ScratchTools/zipball/master). If it downloads a `.zip` file, unpack it. Then, with the folder, go to `chrome://extensions` (On Chromium forks, you will have to replace "chrome" with your browser's name. (eg. `vivaldi://extensions`)), make sure you have developer mode enabled (switch in the top right corner), and drag the downloaded folder onto the page. Make sure you've disabled other versions of ScratchTools.
 - GitHub (Firefox & Firefox Forks): Download from GitHub [here](https://github.com/STForScratch/ScratchTools/zipball/master). If it downloads a `.zip` file, unpack it. Then, with the folder, go to `about:debugging`, click "This Firefox" and click "Load temporary extension".
 > [!WARNING]
-> Extensions loaded this way are indeed temporal, once you close the window, it will be gone - ScratchTools is still outdated on Firefox at the time of writing this, thus the extension will have failures and won't load, this was still put in ahead of time so this warning can be removed later on rather than having to write this out.
