+## Implemented Selectors
+
+For further examples of these selectors head over to [w3schools](
+http://www.w3schools.com/cssref/css_selectors.asp).
+
+```bash
+cat index.html | pup .class
+# '#' indicates comments at the command line so you have to escape it
+cat index.html | pup \#id
+cat index.html | pup element
+cat index.html | pup [attribute]
+cat index.html | pup [attribute=value]
+```
+
+You can mix and match selectors as you wish.
+
+```bash
+cat index.html | pup element#id[attribute=value]
+```
+
+## Flags

+-c --color         print result with color
