+
+## Installation
+
 To install it, run the following commands (Docker must be installed on your system):
 
     $ docker-compose up -d # Download, build and run Docker images
     $ docker-compose exec app bin/console doctrine:schema:create # Create the MySQL schema
 
-Your project will be accessible at the URL `http://127.0.0.1`.
+Your project will be accessible in two different ways:
+* Through the HTTP cache (Varnish): `http://localhost`
+* Through the HTTP server directly (Nginx) to facilitate debugging: `http://localhost:8080`

 Start by [downloading the API Platform Standard Edition archive](https://api.github.com/repos/api-platform/api-platform/zipball) and extract its content.
 The resulting directory contains an empty API Platform project structure. You will add your own code and configuration inside
 it.
 Then, if you do not already have Docker on your computer, [it's the right time to install it](https://www.docker.com/products/overview#/install_the_platform).
