Everything you need to get started. If your question isn't here, ask in the Discord.
Lemon SMP is a Java Edition survival server — one shared world you build in with everyone else. There's a Discord where the community hangs out, and server ranks that come with kits so you don't have to start completely from scratch.
Java Edition 1.21.11. Make sure that's the version selected in your launcher before you connect.
Open Minecraft Java Edition, go to Multiplayer → Add Server, and paste the server address from the home page. Save it, then hit Join Server. Exact connection details are in the address box.
Not right now — Lemon SMP is Java Edition only. Bedrock, mobile, and console clients can't connect.
Ranks are upgrades for the server. They unlock things like kits, nickname, skin and colour changes, and /shout on the higher ranks — the higher you go, the more you get. The full list with prices is on the ranks page.
There's no self-serve checkout yet, so ranks are bought through the Discord: open the ranks page, hit the button on the rank you want, and staff will sort it with you.
The current rules are pinned in the Discord. Read them before you start playing — staff enforce them, and "I didn't know" isn't a defence.
Open a ticket in the Discord. That's where staff and the community are, and it's the fastest way to get something sorted.
