 ## Using a PHP Framework
 
 To demonstrate the usage of Composer, we will install the ZendFramework skeleton application:
 
 1. Delete the `index.cgi` file in the `/public` directory
-2. Download the ZendFramework skeleton application as a `.zip` file from https://github.com/zendframework/ZendSkeletonApplication
-3. Unzip this file at the root of your git repository (i.e., the content of `/public` in the `.zip` must be poured in your local `/public` directory)
-4. Commit and push all modifications
-5. During the git push, Composer will download all dependencies found in `composer.json`
-6. Visit your application's main page (e.g. https://myapp-mydomain.rhcloud.com/)
+2. Rename the `_build file` to `build` in the `/.openshift/action_hooks/` directory if you have not done so already
+3. Commit this file
+4. Make it executable with `git update-index --chmod=+x .openshift/action_hooks/build`
+5. Commit this file again and push it too
+6. Download the ZendFramework skeleton application as a `.zip` file from https://github.com/zendframework/ZendSkeletonApplication
+7. Unzip this file at the root of your git repository (i.e., the content of `/public` in the `.zip` must be poured in your local `/public` directory)

 A similar procedure can be used for other PHP frameworks.
