Hi Mercedes, welcome to KH!
You've come to the right place! At the top of the page here there is a tab for the videos. You'll want to start with learning how to CO (cast on) the stitches, then you can learn to knit. If you can get it from the videos that's great. If you need more help or need something you can print out check these two sites.
http://www.knitpicks.com/Content/index.php
http://learntoknit.lionbrand.com/
Both of those sites and this one have glossaries for terms you don't know. Have fun!
Be sure to look around the forum at all the special forums we have and join in!
