You can pick one of the default SVG icons (http://www.zondicons.com/) provided by Steve Schoger.

Help::make('Title')->icon('help'); // the default one
Help::make('Title')->icon('info');
Help::make('Title')->icon('warning');
Help::make('Title')->icon('danger');
// Load a custom one
Help::make('Love you')
    ->message('Yes, I love you!')
    ->icon('<svg viewBox="0 0 20 20" xmlns="http://www.w3.org/2000/svg"><path d="m10 3.22-.61-.6a5.5 5.5 0 0 0 -7.78 7.77l8.39 8.39 8.39-8.4a5.5 5.5 0 0 0 -7.78-7.77z"/></svg>');
// or show no icon at all
Help::make('Sad')->withoutIcon();

Render html messages

Help::make('Title', 'Message with <a href="#">link</a>')->displayAsHtml();

From v0.2 the displayAsHtml() method applies also to the field name (unless shown as column header on index).

Full width on details screen

// Remove annoing padding in detail screen, also the default behaviour for the heading template 
Help::make('Negative margin')->showFullWidthOnDetail();

With side label

// Show a side label instead of the title on the top
Help::make('Look I\'m on the side')
    ->message('I\'m not...')
    ->withSideLabel();

Show help messages on index

/**
 * By default help messages aren't shown on index,
 * when enabled they are shown as an hoverable 
 * icon showing a plain (no html) tooltip.
 */
Help::make('Column title')
    ->message('Message with <a href="#">link</a>') // The link code will be stripped out on index
    ->alsoOnIndex();
    
// Field icons can be shown conditionally on index
Help::make()->message(function () {
    return $this->name?"{$this->name} is awesome!":null;
})->onlyOnIndex();
