How do I install Minecraft 1.13 Snapshot 18w03b?

Download the client jar and place it in your launcher's versions folder, or use your launcher's version selector if it supports snapshots. For servers, download the server jar and run it like any other Minecraft server.

Will my old worlds work with 1.13 Snapshot 18w03b?

Snapshots can be unstable. Always back up your worlds before loading them in a snapshot. You can still load worlds from earlier 1.13 snapshots, but updates between snapshots may require world regeneration.

What's the difference between the client and server downloads?

The client jar is for single-player worlds. The server jar runs a multiplayer server that players can connect to. Use whichever matches what you're trying to do.

Can I use mods with this snapshot?

Snapshots generally don't have mod support built-in. You'd need a mod loader like Forge to add mods, and most mod developers don't support snapshots since they change frequently.

Is this snapshot stable enough for survival worlds?

Snapshots are experimental. While 18w03b is relatively stable for a snapshot, you should always back up important worlds before trying new snapshots.
