Answer 2

The script can be included in the functions.php file of your active theme. In order for Wordpress functions to be available in your script, you need to include:
The path is specified for the file that lies at the root of the active theme.
And you need to display it on the main page depending on how the topic is arranged for you. If the settings are "your latest entries" joxi.ru/vAWRwgySv6n92W , you need to look at the index.php or home.php file of the theme (depending on the theme, it may be different). If a static page is specified, you need to look at page templates.
There are a lot of different options and nuances.
