 # Build Options
 
+## Selecting a Symfony Skeleton
+
+By default, Symfony Docker will install the minimalist skeleton.
+To install the ["website skeleton"](https://symfony.com/doc/current/setup.html#creating-symfony-applications), use the following command:
+
+    SKELETON=symfony/website-skeleton docker-compose up --build
+
 ## Selecting a Specific Symfony Version
 
 Use the `SYMFONY_VERSION` environment variable to select a specific Symfony version.
 
 For instance, use the following command to install Symfony 4.4:
 
-    $ SYMFONY_VERSION=4.4.* docker-compose up --build
+    SYMFONY_VERSION=4.4.* docker-compose up --build
+
+## Installing Development Versions of Symfony
 
 To install a non-stable version of Symfony, use the `STABILITY` environment variable during the build.
 The value must be [a valid Composer stability option](https://getcomposer.org/doc/04-schema.md#minimum-stability)) .
 
 For instance, use the following command to use the `master` branch of Symfony:
 
-    $ STABILITY=dev docker-compose up --build
+    STABILITY=dev docker-compose up --build
 
 ## Customizing the Server Name
 
 Use the `SERVER_NAME` environment variable to define your custom server name(s).
 
-    $ SERVER_NAME="symfony.wip, caddy:80" docker-compose up --build
+    SERVER_NAME="symfony.wip, caddy:80" docker-compose up --build
 
 If you use Mercure, keep `caddy:80` in the list to allow the PHP container to request the caddy service.
