What should I include in my page to activate the plugin ?
My advice to you is to:
a) Read the documentation:
b) Download/ install / Inspect the Shop Skeleton as that has lightslider installed and working:
Should be like the demo
I have read documentation and I created page lightslider.md but nothing
then try option b) and look at the Shop Skeleton. You can use that as a working example.
If you still have problems, please zip up your entire /user folder put it on dropbox and provide me a link. I can then look at it and see what your doing wrong. It’s kinda hard to debug if you don’t provide step-by-step what you have done.
you can’t just have an entire page that renders the lightslider, you need to have either a modular page, or inject the modular page into a regular page:
page name in the repertory 03.slider include file lightslider and in this flile lightslider ```
title: Slider
file lightslider.md sorry
modular page…
With modular page it’s also creat file lightslider.md
i strongly suggest you install a copy of the shop skeleton to see how it’s used there. Learn by example, is the best way especially with the language barrier we are facing here 
After install lighslider I install shop skeleton
The shop skeleton is a ready-to-go install of Grav, just extract it into a new folder in your webroot and point your browser at it, then you can look at the folders/files to see how it’s setup.
Repertory please ?

shop skeleton it so difficult configuration… as soon as I prefer go to bed now ! Thank-you for your help
message error…
RuntimeException (404)
Template “lightslider.html.twig” is not defined ().
Open: /var/www/system/src/Grav/Common/Twig.php
// Get Twig template layout
$template = $this->template($page->template() . $ext);
try {
$output = $this->twig->render($template, $twig_vars);
} catch (\Twig_Error_Loader $e) {
throw new \RuntimeException($e->getRawMessage(), 404, $e);
}Yah like i said above, it’s a modular page, you can’t use it as a regular full page. Please read the docs on that.
thank-you but too difficult at configuring
