Aura H2O Browser w/o Internet (+ Wikipedia Kiwix)?

[DejaVu123]

1. I was wondering if there is any mod allowing the use of the web browser without having to be connected to the Internet. I have set up a WebPortal (https://www.mobileread.com/forums/sh...d.php?t=262353) but it would be more useful without having to be connected to wifi, therefore I can use it on the go.
I found this (https://www.mobileread.com/forums/sh...4&postcount=26), but I am not sure how I would set this up (I have no coding experience), or if it would work with my firmware (4.19.14123).
2. Secondly, since Wikipedia ZIM file support is not supported on later firmware (and I don't want to downgrade) are there any easy to follow tutorials on how to get 'kiwix-server'. I have seen comments of people setting it up, but no clear instructions. The ZIM file is under 500mb, so shouldn't be constrained by the 2gb file limit.

Any suggestions would be appreciated.
