 # Grab
 
 Grab provides an clean way to fetch multiple values from a hash. Instead of:
 
-```
-def my_method(opts)
-  foo = opts.fetch(:foo)
-  bar = opts.fetch(:bar)
-end
-```
+    def initialize(params)
+      foo = params.fetch(:foo)
+      bar = params.fetch(:bar)
+    end
 
 you can write:
 
-```
-def my_method(opts)
-  foo, bar = opts.grab(:foo, :bar)
-end
-```
+    def initialize(params)
+      foo, bar = params.grab(:foo, :bar)
+    end
+
+or if some of your params are optional:
+
+    def initialize(params)
+      foo, bar = params.values(:foo, :bar)
+    end
