Make sure you have Telegram installed on your mobile device and you’ve signed up with your mobile number. Visit https://comments.app/ and select “Connect Website” on " Comments for websites". It will ask for the number registered to Telegram, put your number in and then go to the app and confirm requested access.
Type your site name and site address and click “Connect Website”. It will then give you a JS embed script which you can place on your blog. You’ll probably want to download your theme and place the code inside post.hbs. Your theme may have a commented out section which looks like the following…
<section class="post-full-comments">
</section>
Remove the “<!--” and “-->” and place the code in between the above code and then save, zip the theme and upload to Ghost. You should now see comments on your blog posts.
