+Some parsers can receive options that modify their behavior. These options are passed in as named arguments to `input`:
+
+**Example:**
 
 ```ruby
 input :start_date, :date, parse_format: '%Y-%m-%d'
 ```
+**Available Options:**
+| Parser      | Option      | Default    | Notes
+| ----------- | ----------- | -----------| -----------
+| `ArrayParser`   | `parse_each`| N/A | Accepts a parser type, then uses that parser to parse each element in the array. If this option is not defined, each element is simply returned.
+| `DateParser`| `parse_format` | `'%m/%d/%Y'`| Accepts any format string accepted by Ruby's `strftime` method
+| `DateTimeParser` | `parse_format` | `'%m/%d/%Y %I:%M:%S %p'` | Accepts any format string accepted by Ruby's `strftime` method
