This example shows how to setup an environment running Rails 3 beta 3 under 1.9.2-head with a 'rails3' gem set.

∴ rvm update --head
# ((Open a new shell)) or do 'rvm reload'

# If you do not already have the ruby interpreter installed, install it:
∴ rvm install 1.9.2-head

# Switch to 1.9.2-head and gemset rails3, create if it doesn't exist. 
∴ rvm --create use 1.9.2-head@rails3
