Steel is a lightweight framework which allows for developers to have a drop-in MVC solution.
To install the framework, you’ll want to make sure that you have a web server with mod_rewrite and PHP 7. (Steel may run on older versions but is developed on PHP 7)
Download the latest version of Steel from https://github.com/EricRabil/steel-framework/archive/master.zip and unzip it to wherever you want to store your web documents. Then, update your web server to make only the public directory available (make it your DocumentRoot)
Now, you can get started on the framework at https://github.com/EricRabil/steel-framework/wiki/Getting-Started
