-This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
+# marcelo.quest
 
-## Getting Started
+My personal website and blog — built with Next.js, MDX, and Tailwind CSS, deployed to AWS via S3 + CloudFront.
 
-First, run the development server:
+## What's in here
 
-```bash
-npm run dev
-# or
-yarn dev
-# or
-pnpm dev
-# or
-bun dev
-```
-
-Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
-
-You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+- **Home** — landing page with bio, contact info, and a fun hover animation
+- **About** — academic and professional background
+- **Research** — publications and research work (cybersecurity & blockchain)
+- **Blog** — posts written in MDX with syntax highlighting via Shiki
 
-This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
+## Tech stack
 
-## Learn More
+- **Framework**: Next.js 15 (App Router) + React 19
+- **Content**: MDX with `next-mdx-remote`, `rehype-pretty-code`, and `rehype-slug`
+- **Styling**: Tailwind CSS + `@tailwindcss/typography`
+- **Deployment**: GitHub Actions → S3 + CloudFront cache invalidation
 
-To learn more about Next.js, take a look at the following resources:
+## Getting started
 
-- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
-- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
-
-You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js) - your feedback and contributions are welcome!
+```bash
+yarn install
+yarn dev
+```
 
-## Deploy on Vercel
+Open [http://localhost:3000](http://localhost:3000) to view it locally.
 
-The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
+## Deployment
 
-Check out our [Next.js deployment documentation](https://nextjs.org/docs/app/building-your-application/deploying) for more details.
+Pushes to `main` automatically trigger a build and deploy via GitHub Actions — the workflow builds the site, syncs to S3, and invalidates the CloudFront distribution.
