@lauriejim for reference these docs are being constructed to allow for easy migration to the new docs layout (based on your recent changes to the docs-v2 branch)

[derrickmehaffy]

@alexandrebodin @lauriejim ready for review. I have tried to keep it as short and simple as possible and just give context to the running config until a documentation writer is brought on.

I could dive a lot deeper into customization but at this point I'm not sure if it's something we should include or not.

That might be better left to a tutorial on https://strapi.io/tutorials or a blog post
