Need help getting copyrighted...

If anyone who is visiting here from the USA has copyrighted their own crochet patterns, I am looking for help getting started. I've been to the copyright website, but there is so much on there I didn't know where to start. I have some patterns I want to copyright. If anyone could email me with a little help getting started, I'd really appreciate it! Just click on "About Me" and email. Thanks! Nancy
