Subject: Understanding Variable Naming in Ruby

I'm trying to better understand how variables are named in Ruby... 
here's what I think I understand. Please correct me where I misunderstand:

#Globals are defined outside a class/method and are
#available everywhere. Must starts with '$'
$global_variable

#Class names must start with capitalized letter.
class Class_name

     #Starts with '@@' and is available to all methods in the class.
     @@class_variable

     #Method name must start with lowercase letter or '_'
     def method_name

         #Must start with '@' similar to Python's self notation.
         #This variable is local to the method.
         @method_variable

     end
end


Where do constants and local variables fit into this?

Thanks,
Brad
