Supply Lines

As you unlock more workshops, it will be a challenge transporting materials from your main workshop (most likely Sanctuary) to the new workshops. New workshops have ample amount of materials you can scrap but it will come to the point that you'll need more materials to primarily build a generator and recruitment beacon and set up its defenses as well.

This problem is addressed by sending a generic settler to a Supply Line. Connected workshops will share materials and resources which will make it easier to build stuff especially on the new workshops. Provisioners also count toward your bed limit and you only need to send one provisioner per workshop. One good practice is to link up a new workshop you unlock or clear to your main workshop and you can start building stuff in it conveniently.
