Allow users to like content on your site. If content supports being likable a ‘thumbs up’ will appear as a social interaction with this content. Liking content will also notify the content owner about the new like. A counter will show next to the like action reporting about the amount of likes the content has. Clicking on the counter will show a list of users who recently liked the content.
The likes plugin uses the entity capability likable. This capability defines if an entity is likable.
