There is a genealogy section on answerbank - it's under history. Lots of helpful people in there if you need more help.
To start though, ask any relatives (especially ones a generation or two older than yourself). They may know quite a lot about your family, and may even have birth/marriage/death certificates you can copy, and maybe photos you could copy aswell. Once you've done that work backwards from what you know. I know that ordering certificates can be quite expensive, but you can glean a lot of information from them. On my fathers side I started with my fathers birth certificate, then got his parents marriage certificate (which gave me both their fathers names), then their birth certificates etc etc. Once you get back to 1911 and before you can check the census. I use findmypast.co.uk and I'm also on genesreunited where I have found a few cousins (one a first cousin I've not seen in 30 years, the others a little more distant).
Good luck, I'm sure you'll enjoy it.
