+### Aliases
+
+To add aliases like `mobile?` and `tablet?` to the base object (e.g `browser.mobile?`), require the `browser/aliases` file and extend the Browser::Base object like the following:
+
+```ruby
+require "browser/aliases"
+Browser::Base.include(Browser::Aliases)
+
+browser = Browser.new("Some user agent")
+browser.mobile? #=> false
 ```
