 - Microsoft edge: You can download for Edge [here](https://microsoftedge.microsoft.com/addons/detail/scratchtools/aaidjeidbnhpjhblbianjeghjopbimmk). You can then just add it to Edge, and then you have ScratchTools!
 - Safari (macOS, iPadOS and iOS): You can build the extension by typing `make` for macOS, and `make ios` for the iOS app (you will have to sign it on  Xcode), make sure you have enabled Developer mode and allowed unsigned extensions.
 - GitHub: 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`, 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.
