How to change index.html meta title?

[nalakawula]

I clone your master branch then add my post and my pages.
The meta title for home page (index.html) is weird, because it use title from about.md.
Kindly check here https://zealous-sammet-315091.netlify.com/, it show

<!-- begin _includes/seo.html --><title>Posts by Collection - sumarsono.com</title>

Posts by Collection is title from about page.

My question is, how to add correct title to my home page without add <h1 id="page-title" class="page__title" itemprop="headline"> in my home page.

Thank you.

You add the page title using YAML Front Matter. The .html or .md file you're using for the Posts by Collection page has a title key that you can modify.

For example, the demo "Posts by Collection" page has the following front matter.

title: "Posts by Collection"

Change the the text to what you want.
