 ### Prerequisites
 
-- Windows (10 tested) or Linux (Debian 9 tested)
+- Windows (11 tested) or Linux (Debian 11 tested)
 - A Ruby `3.1.2`+ (check with `ruby -v`) installation with the Bundler gem (`gem install bundler`). I recommend [rbenv](https://github.com/rbenv/rbenv) to manage Ruby installations on Linux and [RubyInstaller for Windows](https://rubyinstaller.org/downloads/) to install Ruby on Windows.
 - If using this tool to run a server, grab a portable version of [SteamCMD](https://developer.valvesoftware.com/wiki/SteamCMD#Downloading_SteamCMD) (we'll extract it to `ohd-admin-wrapper/steamcmd/installation`)
   - [Windows SteamCMD](https://steamcdn-a.akamaihd.net/client/installer/steamcmd.zip)
   - [Linux SteamCMD](https://steamcdn-a.akamaihd.net/client/installer/steamcmd_linux.tar.gz)
+- Other OHD-specific prerequisites may be required, e.g. `apt install lib32gcc-s1` on Debian 11
