-```txt
-php-fpm:
-    build:
-        context: ./php-fpm
-        dockerfile: Dockerfile-56
-```
+3 - Rename `Dockerfile-56` to `Dockerfile-55`.
 
-3 - Open `php-fpm/Dockerfile-56` file and on the first line replace the PHP version from (`FROM php:5.6-fpm`) to (`FROM php:5.5-fpm`).
+3 - Edit the file `FROM php:5.6-fpm` to `FROM php:5.5-fpm`.
 
-4 - Now you can rebuild the container
+4 - Build an image from `Dockerfile-55`.
+
+5 - Open the `docker-compose.yml` file.
+
+6 - Point `php-fpm` to your `Dockerfile-55` file.
 
-```bash
-docker-compose build php
-```
