Run-Me is a script just for fun!
Make sure that you are signed in your GitHub account, if not do so now!
Open run.user.js at this link here and copy the entire script.
Make sure you are on a tab with an open GitHub page and open developer tools.
To open developer tools on Chrome/Chromium please press ctrl+shift+I
To open developer tools please press ⌘+⌥+I
Click on the Console
tab in the developer tools to open it, then click on the text area in the Console tab.
Ensure you are still on a browser tab that has GitHub open.
Paste the script by pressing ctrl+V if you are on Windows or if you are on macOS press ⌘+V.
Then hit return / Enter.
The script needs to run a few minutes. At the end it will display "Finally Over ;-)". Ensure it runs until the end.
