Thanks for PR, great start,

Please notice that we didn't start programming yet, we only started API spec sheet design,
After that will start DB design,
then we can implements db updates

I will keep this PR for later, in the meantime, you can contribute to API (/apis.yaml)
but since you already submit your PR, I'll review it for you so you can improve it and resubmit it again:

• countries should has a table, so we can use country_id in users table, not country (name)
• for table names, you should use snake_case, like "full_name"
• nullable and unique, are methods, so you should call them like ->nullable() with brackets at the end
• you should create a new db migration file, editing existed file will not reflect your edit unless someone start installing from empty db.

Keep it going, you'll have great skills in no time :)
