This are the protocol files for the NookureStaff project. This files are used to communicate the server with the client browser using the WebSocket protocol and the NeoSocket server.
This uses the protobuf syntax to define the messages that the server and the client will use, this repo is only used to have a git submodule in the main project and browser, so the server and the client can use the same files to generate the code.
Sincerely, it doesn't matter to you, unless you are a developer who wants to create its own implementation or extend the current one. If you are a user, you don't need to worry about this.
