Install a Minecraft SKY (Official) server through the Control Panel (Servers → Select your server → Game servers → Add Game Server → Minecraft SKY (Official))
It is my second time using ScalaCube as a hosting server for Minecraft and what I like the most is how quick they are to respond to any support questions you have. They literally got back to me within an hour of sending the question that I had. The support team also helped me get a new server when I was unable to recover the original one through other means. Would definitely recommend using them to anyone who is new to hosting a server.
