 Amber server is a [nodejs](https://nodejs.org/) application. Most of the runtime parameters can be set using [environment variables]((https://github.com/obiba/amber/blob/main/README.md#environment-variables)). For advanced usage, the runtime settings **can** also be amended by copying a local [./config/production.json](https://github.com/obiba/amber/blob/main/config/production.json) file.
 
 The `Dockerfile` for a production Amber server will then look like: [Amber Server template](https://github.com/obiba/amber-template/tree/master/amber)

-Amber Studio is a [Quasar SPA](https://quasar.dev/quasar-cli-vite/developing-spa/introduction) (single page application) web app delivered by a [NGINX](https://www.nginx.com/) web server. The web app **must** be built with the site specific settings such as the Amber server URL and the [reCAPTCHA](https://developers.google.com/recaptcha/) site key.
-
-Optionally, some source files can be modified as well:
-
-* [settings.json](https://github.com/obiba/amber-studio/blob/main/settings.json) file that is a simple way of tweaking the default theme and for adding new languages.
-* [public](https://github.com/obiba/amber-studio/tree/main/public) folder that contains the app icons.
-* [src/css](https://github.com/obiba/amber-studio/tree/main/src/css) folder that contains the [SCSS](https://sass-lang.com/documentation/syntax) files.
