[Leica] Lightroom merge

[Lew Schwartz]

I don't know how to do this yet:

I have my laptop with my travel/away from home photos I've already edited
in LR.

I want to move those photos, edits etc to my big daddy desktop and merge
the new stuff, LR catalog and all into the LR setup & catalog on my main
machine. I'm able to copy everything onto a sd card, thumb or NAS drive as
an intermediate step.

What steps do I follow?
