Label & Description

The old-fashioned way:
<label for="my_text">Field</label>
[text name="my_text"]
<p>Description</p>

The cool way:
[text name="my_text" label="Field" desc="Description"]

If field is required, will appear an * in the label automatically:
[text* name="my_text" label="Field" desc="Description"]

In addition, if you provide a label attribute, this label will be used in the submissions view.
