Manually Install The Playerlands Rust Plugin
Sign up for PlayerLands at PlayerLands
The first things you are going to need to do is making sure your server has oxide installed and that you are set as an admin, you can find the link for both these things here
Then you will need to download the oxide plugin from the PlayerLands page.
The contents of the .zip file will be 2 folders and a readme file, so just unzip them somewhere on your pc.
Then stop your server and connect to your server via FTP and drop both folders into the main directory, close the FTP connection and restart your server.
Head to your store page and identify your Rust server on the right side of the screen and click the "deploy" button.
Your server is now ready to link to the store.
