Hi,
I’m sorry for delay, I’ve not received the notification of your entry in the support page.
You can insert the shortcode into the content of the post, or directly into the template file used by posts.
To insert the shortcode into the post’s content, simply paste it into the content: [codepeople-post-map]
To insert the shortcode directly into the template file, use the following piece of code:
<?php echo do_shortcode('[codepeople-post-map]'); ?>
If the index page includes the content of posts (and not only their excerpts), each of them will contain its own map, however, you can insert the shortcode directly into the template file used by the index page to display a map with the points defined in all posts loaded by the index page.
Best regards.
