In reply to Emmalouise:
Welcome. It would be a great idea to do a climbing course so as to learn some rope stuff, knots and safety-related things. On top of that a good instructor will show you some climbing techniques; look on it as the same as taking up any movement skills activity like dancing or athletics or skating.
And enjoy! Climbing is about the joy of moving safely on rock, of testing yourself and learning your personal limits, of overcoming fear, of companionship and reliance on self and others, and of course the aesthetic bit of the beauty of the mountains and the outdoors. For some, rock climbing is just one part of mountaineering and for others it's their only sport. Climbing will make you fit and strong and will change your view on the world and your fellow humans.
Get yourself some basic kit, even just a length of rope, and practice the tying-in knots so that they become second nature and you can do them in moments of stress.
Once you've got the basics dialled, start to keep an eye open for a climbing buddy. A good buddy is worth their weight in gold, in any sport or activity.
