How to weave in ends of a scarf?

I am working on a scarf that ends in seed stitch (k1, p1, k1, p1,…) and I was wondering what “bind off and weave in ends” means. Its mom’s sophisticated scarf from SnB Nation. Can anyone help?

You bind off to get the sts off the needle and then you’re left with one. Cut the yarn a few inches from the last stitch then pull the loop so the end comes free. Thread the end/tail through the adjoining sts to hide it.

Thanks so much! I just finished it today, and it came out awesome!
