What about the DB creation? about peewee_migrate

[Thorbijoern]

So, if we use peewee_migrate, we should avoid this command and only use peewee_migrate, right?

basically yes... but it's not completely needed on the first create of the database, for future migrations you should stick to peewee-migrate.

Also, does Peewee_Migrate use Peewee [...] for migrations, right?

yes, peewee-migrate uses the migration features of peewee playhouse.

Any doc about how to create the migration files?

could you atleast read the readme.md? you can create a blank migration file with pw_migrate create.
the available functions are listed in the blank migration file and work pretty much like the migrate functions of playhouse.
