1.Enable LoadModule rewrite_module modules/mod_rewrite.so from your apache

2.Enable extension=php_openssl.dll from your php.ini

3.Install Composer from http://getcomposer.org/doc/00-intro.md#autoloading. There are instructions for both Linux and windows.

4.Download skeleton project from github.( https://github.com/zendframework/ZendSkeletonApplication and click the “Zip” button) to your htdocs.

5.Go to the directory where you have just downloaded the skeleton project.

6.Run php composer.phar install.This will download all the dependencies.

7.Go to http://framework.zend.com/manual/2.2/en/user-guide/skeleton-application.html and create a virtual host accordingly.

<VirtualHost *:80>
  ServerName zf2-tutorial.localhost
DocumentRoot /path/to/zf2-tutorial/public
SetEnv APPLICATION_ENV "development"
<Directory /path/to/zf2-tutorial/public>
    DirectoryIndex index.php
    AllowOverride All
    Order allow,deny
    Allow from all
</Directory>

8.Go to c:\windows\system32\drivers\etc\hosts (Windows)or /etc/hosts(Linux) and add the following lines: 127.0.0.1 zf2-tutorial.localhost localhost

9.Go to http://zf2-tutorial.localhost/ and you should see the welcome page.
