How do I learn Paddy Harmonica?

Hey all, I have never played before, but I was gifted a harmonica for Christmas. The person who got it for me mistakenly got a Paddy tuned one instead of the normal one. What I'd like to know is, can I still follow along with online tutorials? Or will they be wrong because it's the wrong tuning for what they expect? And what about harmonica tabs online?

To reiterate, I'm a total beginner, so I'm quite nervous about learning the wrong things. Thanks in advance!
