https://www.skyverge.com/blog/override-woocommerce-template-file-within-a-plugin/

The normal WooCommerce template loader searches the following locations in order, until a match is found:

• your theme / template path / template name
• your theme / template name
• default path / template name

We’re going to alter this slightly by injecting a search for the template within our own custom plugin (step 3 below), before finally defaulting to the WooCommerce core templates directory:

git cheat-sheet

The git command-line utility has plenty of inconsistencies http://steveko.wordpress.com/2012/02/24/10-things-i-hate-about-git/

A GUI like http://sourcetreeapp.com is often helpful, but staying on the command line usually quicker. This is a list of the commands I use most frequently, listed by funcional category:
