Can't upgrade to rails 5

so I've heard that ruby on rails 5 was out so I decided to upgrade my rails version. I can't figure out the way to use rails 5:

# My current Ruby version
$ ruby -v
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-darwin15]
# My current Rails version
$ rails -v
Rails 4.2.6

When I run gem install rails, it installs the latest version of rails(5.0.0)

$ gem install rails
Password:
Successfully installed rails-5.0.0
Parsing documentation for rails-5.0.0
Done installing documentation for rails after 0 seconds
1 gem installed

And now if I run

$ gem list -l

$ rails -v

Run this:

# To change your ruby version as global
$ rbenv global <ruby version> 
$ rbenv rehash

Try running:

$ rbenv rehash

This should be run when you install a new gem that includes an executable (e.g. rails). If you install the gem rbenv-rehash by Ryan Souza, it can do this for you automatically.
