Installing Custom Map in Rust

First, upload your map to a file hosting service such as Dropbox.
Once your map is uploaded, click on “Share”, then “Create a link”, and finally “Copy link”.
Save this link in an empty text file as you will need it later.
Next, please stop your server and switch it to Advanced mode.
Then, in the white column on the left, click on server.cfg.
Insert the following line:

levelurl "DropboxLink"

Replace DropboxLink with the link to your map.
Replace ?dl=0 in the link with ?dl=1, otherwise the server won’t be able to download the map.
If you have done everything correctly, the line should look like this:

levelurl "https://www.dropbox.com/s/1j5v186m720kmr4/test.map?dl=1"

Once you are finished, click Save and start your server.
