Adding AdminLTE

I know there are several GitHub projects with AdminLTE added to CI, but they tend to go out of date.

It seems like the AdminLTE site points to the existence of these projects as evidence that the two can be integrated, so doesn't feel the need to give instructions.

I have seen some videos where it looks like the action is to drop all the ALTE files into one of the CI folders, and then make some config changes that I couldn't follow.

The problem is that I have a partly functioning CRUD setup with an ALTE menu generated by CrudIgniter, but am missing some features like sortable headers, and Search, and want to make sure that I have the full ALTE package installed before I go trying to add some JS manually to the pages.

Overall, it seems confusing.

Can someone provide or point me to clear written instructions for adding ALTE to a new CI project?  Preferably without one of those pre-integrations, and without Composer.

TIA.
