 I named this Azalea because it sounds like a cool word and this is a cool library. This project was heavily inspired by PrismarineJS.

+Tools for automatically generating code to help with updating Minecraft versions.

+The directory name doesn't start with `azalea-` because it's not a Rust crate.
+
+## Usage
+
+Generate packet:\
+`python newpacket.py [packet id] [clientbound or serverbound] \[game/handshake/login/status\]`\
+This will create a new file in the `azalea-protocol/src/packets/\[state\] directory`. You will probably have to manually fix up the auto generated code.
+
+Migrate to a new Minecraft version:\
+`python migrate.py [new version]`\
+This updates all the packet ids in `azalea-protocol/src/packets/mod.rs` and creates all the new packets.
