the email. Plus it is super simple simple to use _of course after the
initial fumbles trying to design the db and relationships_
Adds `/blog` page with support for `.md` and `.mdx` files.
What we learnt in setting this up will be packages in a package `@nestri/mdx` and used to set up the `/docs` and the `/terms` and `/privacy` routes
