Welcome to the build-in-public blog

⚠️ This is a sample post demonstrating MDX formatting. Edit or delete content/blog/chao-mung.en.mdx and write your real post.

This is where I document the build-in-public journey — building AI-powered language-learning products and sharing what I learn along the way.

How you write a post

Each post is an .mdx file in content/blog/, named slug.vi.mdx (Vietnamese) or slug.en.mdx (English).

The top of the file is frontmatter declaring the title, description, date and tags:

---
title: "Your post title"
description: "A short description for SEO and social sharing."
date: "2026-06-29"
tags: ["learning", "chinese"]
---

What MDX supports

• Bold, italic, and links
• Ordered and unordered lists
• inline code and code blocks
• Blockquotes, tables, images

When you add a post file it automatically shows up on the blog and is included in the sitemap and RSS — no code changes needed.
