Understanding the Project Structure

The blog template gives you a clean starting point:

my-blog/
├── src/
│   ├── content/
│   │   ├── config.ts        # Content schema definitions
│   │   └── blog/            # Your Markdown posts live here
│   ├── layouts/
│   │   └── BlogPost.astro   # Post layout template
│   └── pages/
│       ├── index.astro      # Home page
│       └── blog/
│           └── [...slug].astro  # Dynamic post routes
├── public/                  # Static files (images, favicon, etc.)
└── astro.config.mjs         # Astro configuration

Any .md file you add to src/content/blog/ automatically becomes a blog post. No routing configuration needed.

Writing Your First Post

Create src/content/blog/my-first-post.md:

---
title: "My First Post"
description: "Hello from my new Astro blog."
pubDate: 2026-04-09
heroImage: "/images/first-post.webp"
tags: ["Astro", "Blog"]
---

Write your content here using standard **Markdown** syntax.

## A Subheading

More content...

The frontmatter block (between ---) must match the schema defined in config.ts. If a required field is missing or the type is wrong, the build fails with a helpful error — which is exactly what you want.

Adding Tailwind CSS

For styling, Tailwind CSS pairs perfectly with Astro:

npx astro add tailwind

This single command installs the package, updates astro.config.mjs, and creates tailwind.config.mjs automatically. No manual wiring needed.
