Post-install tasks:

Ensure Dominions 4 is installed to /opt/Dominions4. If you installed it from the Steam GUI with the default library path, use:

  sudo cp -R ~/.local/share/Steam/steamapps/common/Dominions4 /opt

If you installed it via SteamCMD (see README.md in the Git repository for instructions on doing that if you're starting from scratch):

  sudo cp -R ~/Steam/steamapps/common/Dominions4 /opt

If you can't find it at either of those locations, try 'locate dom4.sh' (if you *just* installed Dominions 4, 'sudo updatedb' first). This should output one line with the full path and filename of 'dom4.sh'. 'sudo cp -R' the path, excluding the filename.

Your install directory must have a 'dom4key' file present containing your Dominions 4 license key. If the file does not already exist, you can create it using the license information from Steam.

To begin setting up hosting, run 'dom4'.
