HelperOptions
This helper is used to generate a configuration form, the values of which are stored in the configuration table. Example: the "Preferences" page.
Options declaration

['info'] => $this->l('Display as info'), // Displays an unstyled text above the fields.
'fields' => array( // The various option fields.

Basic declaration
Removing all the optional fields, this is how to build a basic HelperOptions element:
$this->fields_options = array(
'general' => array(
'title' => $this->l('Parameters'),
'fields' => array(
'PS_MYMODULE_OPTION1' => array(
'title' => $this->l('Choose one'),
'desc' => $this->l('Choose between Yes and No.'),
'cast' => 'boolval',
'type' => 'bool'
),
'PS_MYMODULE_OPTION2' => array(
'title' => $this->l('Add some text'),
'desc' => $this->l('This is where you can add some text'),
'cast' => 'strval',
'type' => 'text',
'size' => '10'
)
)
)
);
