While the official Drupal 8 setup guide is quite comprehensive, it is also a bit overwhelming. So here I'm sharing my steps:

Notes 

I'm on a Debian Linux Server with Apache2 and PHP 7.0 and assume that those are setup accordingly. 

I also assume that Composer and Drush are already set up in a globally accessible location, e.g. /usr/local/bin (I will write a later article that explains their setup.)
