Copy the VPS details from your provider
Keep the provider page open. Studio only needs the server IP, SSH username, SSH port, and the first-login password if the server does not already have your SSH key.
Studio is checking whether meridian studio is running on this computer.
Skip typing when this computer already knows a VPS.
Quick answers
What is a VPS?
A small rented Linux server. Meridian connects to it by SSH and installs VPN services there.
What is a public IP?
The internet-facing address for the server. Examples use addresses like 198.51.100.10.
What if I only have a password?
That is enough for Local Studio. It can use the password once to install a safer SSH key.
