''[[Minecraft: Java Edition]]'' is one of the two [[Minecraft:edition]]s of ''[[Minecraft:Minecraft]]'' written in {{w|Java}} and depends on the ''[[Minecraft:Minecraft Launcher]]'' to download, update, and play. Most of the new development projects focus on either creating entirely new programs from scratch that interoperate with ''Minecraft'' (such as a bot or server) or [[Minecraft:mod]]ding projects that integrate with the game's [[Minecraft:client.jar|client]] or [[Minecraft:server.jar|server]] and provide bug fixes, new features, and several enhancements to existing features.

== Documentation ==
There are ongoing efforts to keep reverse engineered documentation updated, but it isn't as easy as it sounds. The protocol generally changes slightly with each release. Below are links to the current documentation segments, which may or may not be completely up to date.
