Kohana installation and learning version 2.3.4?

Question

Kohana

Hello, you need to study and install kohana version 2.3.4
There is a dock https://kohana234.misty-stix.com/ , but the link to download kohana does not work in it.
I found a link to the required version on github, but I’m reading something in the doc and I can’t find some files in this thing https://github.com/vijinho/kohana2-legacy , for example, there are no models in application and something else was missing. But I didn’t dig deeper, so I think maybe even something like this will meet.
So, the question is what to do? How to learn kohanu exactly version 2.3.4. and install its desired version with the necessary files? I didn’t seem to find anything else on the github, I didn’t find this version in the composer either, and the link doesn’t work in the dock with the site ..
