-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).
+# Portfolio Website v2
 
-## Getting Started
+## Setup
 
-First, run the development server:
+### Domain Records
 
-```bash
-npm run dev
-# or
-yarn dev
-# or
-pnpm dev
-# or
-bun dev
+- Create one A record
+
+### Reverse Proxy
+
+- It doesn't matter what reverse proxy you use (Nginx, Apache, Traefik, Caddy, etc)
+- Point the record to the web port (default: 3000)
+
+### [Docker Compose](./docker-compose.yml)
+
+```yaml
+services:
+  portfolio:
+    container_name: portfolio
+    image: git.altaiar.dev/ahmed/portfolio-2:latest
+    network_mode: bridge
+    restart: unless-stopped
+    volumes:
+      - config:/app/public/config
+      - images:/app/public/images
+    ports:
+      - 3000:3000
+
+volumes:
+  config: # Place config.json and resume.pdf here
+  images: # Place images here
 ```
 
-Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+(Optional) Replace volumes with bind mounts according to your setup
 
-You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+## Configuration
 
-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.
-
-## Learn More
-
-To learn more about Next.js, take a look at the following resources:
-
-- [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!
-
-## Deploy on Vercel
-
-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.
-
-Check out our [Next.js deployment documentation](https://nextjs.org/docs/app/building-your-application/deploying) for more details.
+- The only required field is `name`, a two string array for first and last
+- See [instrumentation.ts](./src/instrumentation.ts#L18-L89) or [config.d.ts](./src/types/config.d.ts) for possible values
+- Validation is performed on container start, and will exit if anything is invalid
