How do I find the version of Ubuntu I am currently using?

I know this sounds incredibly stupid. But i cannot remember what version I am using..and i think that might be the first step to overcoming all my other Ubuntu woes. :/

If anyone would like to help me, i need step by step instructions on how to find this information. I am Ubuntu illiterate...
