Get London theme homepage to show tags instead of articles

I’m not sure if this is a stupid question or not, but I was wondering if there was any way to get the homepage on the London theme to display the tags instead of articles/posts?

I love the layout, but instead of getting the reader to see the most recent posts, I’d rather they see tags and navigate from there.

Thank you!

Yes, it is possible, but you need some basic knowledge of hbs.
You will need to edit the index.hbs file.

There you have a post-feed section.

Instead of that you would have to fetch the tags and list them:

{{#get "tags" limit="all" include="count.posts" order="count.posts desc"}}
    {{#foreach tags}}
       render each tag here..

If you want the same layout as for the posts you would need to define a new partial (tag-card.hbs) and you can take a look how the post-card.hbs as an example and adapt it for the tag context.
