How to create a homepage?

I just started using Strapi for the first time, and I use Astro for the front-end. I created a ./src/pages/[slug].astro file, and it works for pages with a slug. But when I browser to the Astro instance without using a slug (/), then I get a 404.

This is my slug file:

---
import fetchApi from '../lib/strapi';
import type Page from '../interfaces/page';
import Layout from '../layouts/Layout.astro';

export async function getStaticPaths() {
    const pages = await fetchApi<Page[]>({
        endpoint: 'pages',
        wrappedByKey: 'data',
    });

    return pages.map((page) => ({
        params: { slug: page.attributes.slug },
        props: page,
    }));
}
type Props = Page;

const page = Astro.props;
---

<Layout title={page.attributes.title}>
    <section>
        <div class='prose prose-base mx-auto'>
            <h1>{page.attributes.title}</h1>
        </div>
    </section>
</Layout>

I believe I can create an index.astro file where I fetch a specific page, but I don’t know if that’s the best approach.
