 =head1 DESCRIPTION
 
+Set up a form object with new().  The HTML for the opening and closing
+C<< <form> >> tags are returned by the start() and stop() methods.
+
+The L<hidden>, L<text>, L<select>, L<radio>, and L<check> methods all
+correspond to various input types.  The first argument is always the mandatory
+name, and a hash ref as the last argument can optionally be provided for
+additional attributes/options.  Everything is properly escaped.
+
 =over
 
 =item C<hidden>
 
-	$input->hidden(name => 'value');
+Returns the HTML for a simple C<< <input type="hidden"> >> with specified name
+and value (both are required by HTML specs).
+
+	$input->hidden('name', 'value');
+
+As with all methods, a final hash ref can be given to add further attributes.
+While rarely needed in this case, it can also be used as an override or
+alternative to value and name:
+
+	$input->hidden({name => 'name', value => 'value'})
 
 =item C<text>
 
-	$input->text(name => 'default');
+The common C<< <input type="text"> >>.
+
+	$input->text('name', 'default');
+
+If the I<rows> option is set, substitutes a similarly set up C<< <textarea> >>:
+
+	$input->text('name', 'default', {rows => 4});
 
 =item C<select>
 
-	$input->select(name => ['option'], 'default');
+	$input->select('name', ['option'], 'default');
+
+Provides C<< <select><option> >> dropdown by default, but can also output
+multiple C<< <input> >> tags if a I<type> is provided:
+
+	$input->select('name', ['1'], {type => 'checkbox'});
+
+In scalar context, options are joined together by C<$,> (C<$OUTPUT_FIELD_SEPARATOR>).
+Otherwise a list of tags is returned.
+
+Each option can be given as either a simple string containing its I<value>,
+or a hash ref with custom attributes.
+When there's no parent tag (only C<< <input> >>s), a fourth parameter can
+provide common options which will be inherited by each element.  Otherwise,
+options will apply to either the C<< <select> >> or an C<< <option> >>.
+
+The default value (either as a third scalar parameter, or with the general
+I<value> option) will be matched to the value of each option, and if equal,
+its I<selected> or I<checked> attribute will be set as appropriate.
 
 =item C<radio>
 
-	$input->radio(name => ['option'], ['option label'], 'default');
+In fact just a shorthand to L<select> with a preset type of I<radio>, but takes
+an additional third argument to easily set the label for each option:
+
+	$input->radio('name', ['option'], ['option label'], 'default');

-	$input->check(name => ['label', 'second option'], [0, 1]);
+Also a L<select> shorthand, but with a I<checkbox> type.
+Instead of values, the second argument specifies option I<label>s.
+The values by default are set to an auto-incrementing number starting with 1.
+
+Furthermore, the I<checked> status for each option can be specified by a third
+argument.  Either a single boolean value defining all rows, or an array ref
+with the value for each row in order.
