Letters of Recommendation

My teacher gave me a paper copy for my letter of recommendation, but I do not know how to send it through the common app. He told me I could upload it to parchment and send it that way, but I cant figure out how to. Does anyone know what I can do?
Thanks!

If you have a scanner (if you don’t I’m sure your school does) you can scan it, save it to your computer then go on the recommenders page and add it through there. But, colleges look at things like that coming from a student as sometimes unofficial since you could have altered it. They like to see it come directly from a teacher. So I would add him as a recommender then have him scan it and send it through common app.
