Instagram 001, anyone?

I created an Instagram account a few weeks ago so I could see the makeup creations of someone George Takei posted about, but didn't touch the account again until this morning.  To my surprise, I've got 15 followers!  They must be disappointed in me; I have no clue how to use Instagram and haven't posted a thing.  Guess I'll hafta do an online search to find an Instagram how-to, or reach out to one of those followers for some instruction. 😊
