Creating my own website, need help

Tweet

I've been thinking about a certain concept on writing and I want to create my own website around this concept. But I don't know the first thing about creating my own website. Can anyone give me advice on, like, what books to read about website creation, how do I go about posting my website on the internet, etc? Is it true that I have to pay for website space on the Internet? How do I register my domain name? And if I post writings on the website, how do I protect them from copyright infringement? Thanks!
