-.. rubric:: What do you need to do in order to use Multi-User through internet?
-
-1. Use Hamachi or ZeroTier (I prefer Hamachi) and create a network.
-2. All participants need to join this network.
-3. Go to Blender and install Multi-User in the preferneces.
-4. Setup and start the session:
-
-    * **Host**: After activating Multi-User as an Add-On, press N and go on Multi-User.
-    Then, put the IP of your network where IP is asked for.
-    Leave Port and IPC Port on default(5555 and 5561). Increase the Timeout(ms) if the connection is not stable.
-    Then press on "host".
-
-    * **Guest**: After activating Multi-User as an Add-On, press N and go to Multi-User
-    Then, put the IP of your network where IP is asked for. 
-    Leave Port and IPC Port on default(5555 and 5561)(Simpler, put the same information that the host is using. 
-    BUT,it needs 4 ports for communication. Therefore, you need to put 5555+count of guests [up to 4]. ). 
-    Increase the Timeout(ms) if the connection is not stable. Then press on "connexion".
-
-.. rubric:: What do you need to check if you can't host?
-
-You need to check, if the IP and all ports are correct. If it's not loading, because you laoded a project before hosting, it's not your fault.
-Then the version is not sable yet (the project contains data, that is not made stable yet).
-
-.. rubric:: What do you need to check if you can't connect?
-
-Check, if you are connected to the network (VPN) of the host. Also, check if you have all of the information like the host has.
-Maybe you have different versions (which shouldn't be the case after Auto-Updater is introduced). 
-
-.. rubric:: You are connected, but you dont see anything?
-
-After pressing N, go presence overlay and check the box. 
-Also, go down and uncheck the box "Show only owned"(unless you need privacy ( ͡° ͜ʖ ͡°) ).
-
-If it's still not working, hit the support channel on the discord channel "multi-user". This little helping text is produced by my own experience 
-(Ultr-X).
-In order to bring attention to other problems, please @ me on the support channel. Every problem brought to me will be documentated to optimize and update this text.
-Thank you and have fun with Multi-User, brought to you by "swann".
