+A helper ".lookup" method is provided on top of Array's usual tools, and it is a shortcut for `find { |x| x.username == username }`. As such, you can use it to look somebody up by their username:
+
+```
+employees = Linodians.new
+my_friend = employees.lookup('caker')
+```

 #### Loading in existing data
 
 If you already have a hash of data, like one created with `Linodians.new.to_json`, you can import it back in when making a new Linodians object:
 
 ```
 require 'linodians'
 require 'json'
 
 data = File.open('data.json') { |fh| JSON.parse fh }
-linodians = Linodians.new(data)
+employees = Linodians.new(data)
 ```
 
 ## Installation
 
     gem install linodians
