To whom this may concern,
In order to remove the “Free sample” link from the Lil-Let’s hub/home page, simple change the teaser above to anything other than “sample_hero”. Probably best just to put a blank space.
By doing so, the hero image will also be changed (so there isn’t a big gap where the button used to be).
How it works:
The symfony template takes the teaser above and assigns it as a css classname to the div that holds the hero image (as a css background image).
The template also uses this in a select statement to determine whether to insert the sample link or not.
