How can I add @adonis/core types to my project?

I’d like to set up @adonisjs/core in my project so I can test and use it.

I used @adonisjs/mrm to set up the project base, I installed @adonisjs/core, I set up typescript and tslint, but I can’t configure @adonis/core types
that generates many errors.

@adonisjs/core is for v5 and it’s WIP
