I'm new to C5 and I need to develop some custom blocks for my web application. I have experience with php, js, css, etc. but I know very little about the C5 architecture.

Can anyone advice me on the best way to get started? I've looked at the "Creating a New Block Type" How-To, which is a good starting point, but it only covers the absolute basics. Are there any other tutorials that could walk me through creating a more complicated block? Are there any other specific How-Tos you suggest I cover before trying to build my own block?

Thanks in advance!
