1. First, when you are at the menu screen, click the place where you want all your players to be (e.g. Condo, Plaza).
2. There will then be a host option. If you know how to portforward, than forward the port ‘7777’. If not, use this guide to help you.
3. Once that’s all setup, click the ‘create’ button.
4. People will need your IP to join. Go to ipchicken and copy the address.
5. Give the address to anyone who you want to join, or just simply post it on the forums.
Hope this helped!
