-## DigitalOcean Marketplace
+## Provider Options
 
-Deploy Pangolin with a single click using the DigitalOcean marketplace. The one-click installer automatically provisions a DigitalOcean droplet with Pangolin pre-installed and firewall rules configured.
+Most general-purpose VPS providers will work well for Pangolin. Look for a provider with reliable uptime, a data center near your users, clear bandwidth limits, snapshots or backups, and the ability to open inbound TCP ports 80 and 443 plus the WireGuard UDP port configured during installation.
