Help with Lightroom

A trip into Barnsley to help a friend to better understand how Lightroom works.  It's not the most intuitive of software programmes  and people often don'y understand how it 's cataloguing set-up works.  I think it helped that I went to her house, so we could access what she had stored online.  She's always muddled up Lightroom (the cloud version) and Lightroom Classic and I guess being at home with her I was able to help her begin to sort this out.  We also found a few photos to edit.
