+~~~~~~~~~~~~~
+
+The ``help_text`` argument lets you specify descriptive text for this
+``Field``. If you provide ``help_text``, it will be displayed next to the
+``Field`` when the ``Field`` is rendered in a ``Form``.
+
+Here's a full example ``Form`` that implements ``help_text`` for two of its
+fields. We've specified ``auto_id=False`` to simplify the output::
+
+    >>> class HelpTextContactForm(forms.Form):
+    ...     subject = forms.CharField(max_length=100, help_text='100 characters max.')
+    ...     message = forms.CharField()
+    ...     sender = forms.EmailField(help_text='A valid e-mail address, please.')
+    ...     cc_myself = forms.BooleanField()
+    >>> f = HelpTextContactForm(auto_id=False)
+    >>> print f.as_table()
+    <tr><th>Subject:</th><td><input type="text" name="subject" maxlength="100" /><br />100 characters max.</td></tr>
+    <tr><th>Message:</th><td><input type="text" name="message" /></td></tr>
+    <tr><th>Sender:</th><td><input type="text" name="sender" /><br />A valid e-mail address, please.</td></tr>
+    <tr><th>Cc myself:</th><td><input type="checkbox" name="cc_myself" /></td></tr>
+    >>> print f.as_ul()
+    <li>Subject: <input type="text" name="subject" maxlength="100" /> 100 characters max.</li>
+    <li>Message: <input type="text" name="message" /></li>
+    <li>Sender: <input type="text" name="sender" /> A valid e-mail address, please.</li>
+    <li>Cc myself: <input type="checkbox" name="cc_myself" /></li>
+    >>> print f.as_p()
+    <p>Subject: <input type="text" name="subject" maxlength="100" /> 100 characters max.</p>
+    <p>Message: <input type="text" name="message" /></p>
+    <p>Sender: <input type="text" name="sender" /> A valid e-mail address, please.</p>
+    <p>Cc myself: <input type="checkbox" name="cc_myself" /></p>
