Twitter... help?

I know I haven't posted in a couple of days and I'll get to updating later today or tomorrow, I promise! I also have something kind of cool (to me, anyway :)) planned that I want to start soon, so I might start that the next time I update, as well.

However, I'm coming to you now for help about Twitter. I finally got it to link to my phone, which I was having trouble with because it kept registering my number as international and would not verify. I got that sorted out, but now I'm wondering- how do I put it on the sidebar of my blog? I'm sure the FAQs on Twitter.com would answer this, but the page won't load for me. So, wise bloggy friends, can you instruct me on how to do this? I would be forever grateful!
