Beginner’s luck

Submitted to Show Off

I bought my Dremel to help file down cut glass tile I cut with nippers as I'm afraid of a tile saw! 
I love it but I need help learning how to use this thing, what the attachments are for, and how to attach them. Ive looked for tutorials on basic Dremel 101 stuff, but can’t seem to find any. Any suggestions?  I really want to sharpen pruners and garden tools and cant even figure out how to attach the pruner thing! Help! Thanks!
