Bug Bolt Documentation Formatting Issues and Missing Images

Trying to get started with Bolt (in a little 2020.3 test project) and am having issues with the documentation itself. For example, this page appears to be missing several images:

http://docs.unity3d.com/bolt/1.4/manual/bolt-debugging.html

It's hardly the only one. Several pages of the documentation have broken .gifs or just references in the text to images which are not included on the page. I figured it was a problem with my web browser (Firefox 89.0.2, macOS 11.5) but I've cleared the cache and reloaded and also tried in Safari on the same system as well as on my phone, with the same result.

Is this documentation copied from an original source that might be more complete? I understand that Bolt was a 3rd party product which Unity has purchased.

I've also noticed some formatting errors and typos, although this is less of an impediment to getting started.

 

Wayback Machine to the rescue:

This is for 2021, but the documentation is basically the same -- just a few naming changes here and there.
