<h4>How it works</h4>
<p>This script downloads selected release from <a href="https://github.com/joomla/joomla-cms/releases">Joomla! Github repository</a>, unpacks it, creates <code>.htaccess</code>, removes itself and then redirects you to Joomla! installation. In short: just select version and click install to run Joomla! installer.</p>
