Just published a new repository on github: Sitecore Reference Solution to demonstrate concepts I tend to use on most of my projects: Use of Helix, Unicorn, Gulp, Creating SXA Components, Repositories, Dependency Injections and SXA Module Bootstrapping to name a few.

I recorded a set of short videos to discuss different aspects of it, all linked to in the Github Readme.

Take a look and let me know what you think and if there are any other areas that would be useful to add/cover.
