Consistency between INIT.md and MIGRATE.md

@ev1stensberg
To get started on this, it seems like it would be a matter of taking a webpack v1 based config, running migrate on it, and documenting the general experience?

Yep, that's correct. Align with @okonet & @pksjce with this, so that you have enough context in the readme 👍
