 # Workshop Tool
 This is a tool which allows batch upload and download of mods for both [Space Engineers](https://store.steampowered.com/app/244850) and [Medieval Engineers](https://store.steampowered.com/app/333950).  
 It is also known as SEWT (for Space Engineers Workshop Tool), or MEWT (Medieval Engineers Workshop Tool).
