Installation

I use template LEFTSIDE and placed rencontre code into index.php of theme at the bottom. See below:
Is this correct?

/*
* The template for homepage.
*/
?>

<?php get_header(); ?>
<div id=”content”>
<?php if ( have_posts() ) : ?>

<?php while ( have_posts() ) : the_post(); ?>
<?php get_template_part( ‘content-list’ ); ?>
<?php endwhile; ?>

<div class=”post-nav”>
<?php next_posts_link(); ?>
<?php previous_posts_link(); ?>
</div>

<?php else: ?>
<?php get_template_part( ‘content-none’ ); ?>

<?php endif; ?>
</div>
<?php if(is_user_logged_in()) {
$renc=new RencontreWidget;

$renc->widget(0,0);} ?>
<?php get_footer(); ?>

and I place code in header.php of my theme see below at the bottom:
————————— —–
<?php if ( is_front_page() ) {?>
<?php if ( get_header_image() ) {?>
<div id=”header-image”>
<img src=”<?php echo get_header_image(); ?>” class=”header-img” alt=”<?php echo esc_attr( get_bloginfo( ‘name’, ‘display’ ) ); ?>” />
</div>
<?php } ?>
<?php } ?>

<?php Rencontre::f_login(); ?>

A “login” shows at the top of my home page. Is this right?

But I see nothing else on home page. It is empty. Is this normal?
