Help with starting a Podcast!

Hello!

I am wanting to start a podcast, but I am afraid I have no idea exactly how to.. I have spent quite a bit of time researching the easiest most effective way to start a podcast and upload it to Itunes, but in the end just feel more confused..

SO here is my simple question..

What do I need to do to start a Podcast and upload it to Itunes?

I bought a top of the line microphone, and have been messing around in gargeband to record it, but after that I am completely lost as to the next steps..

Thanks soo much to anyone with advice!
