Don't Starve Together - How to Add Shards ?

Hello there,
Can someone please explain to me how to add Shards into the DST world.

I did chose the "shard option" on the server configuration.
But then there is many things to fullfy tha ti don't understand.
What is the cluster key ? Where to find it ? Is this the same as the Token Key ?
What ip enter to the thing ?
Is the Name that i Have to enter after that is a name of my own choice or a specific type of name ?

I checked the Wiki bt still, can't understand how to do. Thank you for answers.

Oh, thank you a lot, i did check the whole thing but it's only if you wanna create from A to Z your own. I can't use it for what nitrado asks but i'll try some other things from that point.

Hey. I took a screenshot of the nitrado section for the shards. I did try what was recommanded on the steam post with the ip + port and even after reinstalling the server + import the whole configuration and restarting the server, still no cave.

On this screen i cleared all port + ip + use the cluster key as password - but not sure what it is. The "token key" of the server is already entered above this configuration. The server is totally working without caves for now.

I'm seriously close to ask for a refund as I feel this so complicated to only add caves into the main game, it's not even a mod.

Is there a nice Nitrado Dev. around here who can explain me how to add these cave pls ? Already more than a week that i need this and pretty sure it's a 5 minutes deal. Thank you for answers.

To have a Do not Starve Together Server with Caves The following things are required:

• 2 Nitrado Game servers, on which the game Don't Starve Together is installed. One of these servers becomes the master and one of the slave servers.
  
  
  Seriously ? It's a main game feature !
  
  thank you for answers anyway
