Layout Plugin - Dead Document Links

Hi

I’m looking to use the Layouts Plugin (specially coupled with Events, Categories and Topics layout plugins) - i know it’s unsupported/being developed for the latest version, but was hoping to read up/experiment in the meantime.

When exploring the documentation in both here and in the githubs - there is a lot of dead links (pointing to pluginmanager.org, or to posts on here that no longer exist - for example, how to install the Event Layout plugin)
