General tutorial "how to use RVM", starting simple with basics of shell usage and going into details including deployment and server configuration.
There are multiple ways to use RVM I want to tell about them not avoiding tricks that save time.
I will also try to mention most common problems and the best ways of avoiding them.
When you get it working it all seems simple, but many users gets confused when it comes to more advanced setups - this will show the best proofed setups.
What will there (roughly) be in your talk that the excellent RVM documentation doesn't cover already? Or put differently: Why should I attend this talk and not just read through the documentation – especially when it comes to server configuration which should be "perfect" anyway?
