Describe the bug
When opening the admin the landing page always shows the same welcome message prompting you to create your first content-type, even if you already have content-types created

Steps to reproduce the behavior
open the admin page

Expected behavior
different messaging should be displayed here
the button to prompt creating content-types shouldn't be allowed on prod

We use redux-optimist only for the editorial workflow which is inconsistent with the rest of the codebase, and makes the code more complicated.
Also, that package is no longer maintained.

We should remove it as unless we can think of a major benefit it produces.

Summary

Add a site AMP version.

Basic example

Nuxt.js has an example: https://github.com/nuxt/nuxt.js/tree/dev/examples/with-amp
Gatsby AMP Plugin: https://www.gatsbyjs.org/packages/gatsby-plugin-amp/

Motivation

The AMP Project support is very important to accessibility and Google's Pagerank. So, it could will be awesome had this support in Gridsome.

Hey Aldo,

Had a suggestion from @schickling that diagnostics is a rather difficult command to spell, and I agree, he made a suggestion to rename it "doctor" which I really like, thoughts?

An example of this is brew doctor.

TODO

• Alias diagnostics command to check.

When installing Ghost there isn't an option to specify a custom database port for MySQL. If you're installing it on a managed database service that runs on a non-standard MySQL port this means you have to install ghost initially and let it fail, then manually edit the config.production.json file and add the port, then restart ghost.
