+## About the Site
+
+This repository contains the source of the **okdp.io** marketing website, a bilingual (FR/EN) static site showcasing the OKDP platform, its architecture, modules, and roadmap.
 
 ## Development
 
 ```bash
 # Install dependencies
 npm install
-# Run the development server
+
+# Generate HTML from templates, then start the dev server
 npm run dev
 ```
+
+`npm run dev` runs two steps in sequence:
+1. `npm run generate`: compiles Handlebars templates with locale data from `src/locales`
+2. `vite`: starts the dev server with hot reload
+
+## Build
+
+```bash
+npm run build   # generate + vite build -> outputs to dist/
+npm run preview # preview the production build locally
+```
