Do I need any technical knowledge to use LuckyChunk?

Nope. If you can buy something online, you can set up a LuckyChunk server. You pick a version, pay, and you've got a server address to share. The management panel is just buttons — change the version, add someone to the whitelist, reset the world. No terminal, no config files. For how your friends actually connect once you have the address, see our guide on How to Join a Minecraft Server.
