Packet documentation

In this folder you find the documentation of the packet messages which are getting exchanged between client and server.

As stated in the project readme, the primary protocol is the ENG (english version) of Season 6 Episode 3.

There is one file for each packet. The packet documentation is generated through XSLT. The source XML files are at MUnique.OpenMU.Network.Packets.

In case you want to contribute packet documentations, please extend these source files accordingly. If you want to build the markdown files as well, you need to install NodeJS 16+ and rebuild the MUnique.OpenMU.Network.Packets project.
