Of course, there are some cases where there's no problem in running the previous steps multiple times, in that case, it's a lot easier to handle.

Also, keep in mind that depending on your setup, in some cases you **might not even need any previous steps** before starting your application.

In that case, you wouldn't have to worry about any of this. 🤷
