Presumably the codex is stored in files used by the client. Use those files to auto generate, so they are easy to keep in sync, a website equivalent.
It would be nice to be able to read up on the game without having to be in the game. Things to do while server on maintenance and while waiting in the queue.
Also to be able able to read it on my second monitor even when in game.
Put it behind authorisation on the website if you want people to have a subscription to read it. Since NDA drop I don't think this would be needed though.
