-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).
+# AI Growth Technologies — website
 
-## Getting Started
+Next.js 16 (App Router) site for aigrowthtechnologies.com.
 
-First, run the development server:
+## Local development
 
 ```bash
-npm run dev
+npm ci
-# or
+npm run dev          # http://localhost:3000
-yarn dev
-# or
-pnpm dev
-# or
-bun dev
 ```
 
-Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+## Environment variables
 
-You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+Copy `.env.example` to `.env.production` (or `.env.local` for development) and fill it in.
 
-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.
+| Variable | Required | Purpose |
+|---|---|---|
+| `RESEND_API_KEY` | yes | Resend key with sending access to `aigrowthtechnologies.com`. Without it the contact form shows an error. |
+| `CONTACT_FROM` | yes | Sender, on the domain verified in Resend: `AI Growth Website <hello@aigrowthtechnologies.com>` |
+| `CONTACT_TO` | no | Inbox that receives enquiries. Defaults to `rey@aigrowth360.io`. |
+| `TURNSTILE_SECRET_KEY` / `NEXT_PUBLIC_TURNSTILE_SITE_KEY` | no | Cloudflare Turnstile. When both are set, the form shows the challenge. `NEXT_PUBLIC_*` values are baked in at build time, so rebuild after changing it. |
 
-## Learn More
+## Deploying to a VPS
 
-To learn more about Next.js, take a look at the following resources:
+Requirements: Node.js 20.9 or newer (22 LTS recommended), npm, nginx, and a process manager such as pm2.
 
-- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+```bash
-- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+git clone https://github.com/AlejandroVeras/aigrowth-website.git
+cd aigrowth-website
+cp .env.example .env.production   # then edit it
+npm ci
+npm run build
+pm2 start npm --name aigrowth-website -- start -- -p 3000
+pm2 save && pm2 startup           # restart on reboot
+```
 
-You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js) - your feedback and contributions are welcome!
+To update later:
 
-## Deploy on Vercel
+```bash
+git pull && npm ci && npm run build && pm2 restart aigrowth-website
+```
 
-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.
+### nginx
 
-Check out our [Next.js deployment documentation](https://nextjs.org/docs/app/building-your-application/deploying) for more details.
+Put nginx in front of the Node server and turn off buffering so streamed pages arrive progressively:
+
+```nginx
+server {
+    server_name aigrowthtechnologies.com www.aigrowthtechnologies.com;
+
+    location / {
+        proxy_pass http://127.0.0.1:3000;
+        proxy_http_version 1.1;
+        proxy_set_header Host $host;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection "upgrade";
+        proxy_buffering off;
+    }
+}
+```
+
+Then issue HTTPS with `sudo certbot --nginx -d aigrowthtechnologies.com -d www.aigrowthtechnologies.com`.
+
+### DNS
+
+At Hostinger, point the `A` records for `@` and `www` to the VPS IP. Leave the MX records (Titan email) and the Resend
+records (`send`, `resend._domainkey`) as they are.
+
+## Content
+
+Inner pages are generated from the Word copy decks:
+
+```bash
+python3 -E scripts/convert-docs.py "<folder with the .docx files>"
+```
+
+This rewrites `src/content/pages/*.json`. The homepage (`src/app/page.tsx`) is written by hand.
