Unassigned settlers will typically assign themselves to tend crops, but this doesn't always happen, so it's a good idea to double-check. A settler also needs to be assigned for the crop to count towards the food supply. There are several crops behind the yellow house in the middle of Sanctuary that can be harvested to obtain the required materials.

After completing each objective, the Sole Survivor will need to speak to Sturges again to receive the next one (even if they build everything ahead of time).

As they build, the Pip-Boy will track their progress. The Sole Survivor will need to use the settlement workshop to build the appropriate settlement buildings to provide for each need.

If they agree to help, Sturges will offer a series of four tasks to complete for the settlement: providing beds, water, food, and finally defenses for the people of Sanctuary. To start the quest, the Sole Survivor must talk to Sturges, who will ask if they're willing to do some work. After the Sole Survivor agrees (completing When Freedom Calls and beginning The First Step), Preston will mention that Sturges could use some help as well. Upon returning to Sanctuary Hills at the end of When Freedom Calls, Preston Garvey will approach the Sole Survivor and ask them to help rebuild the Minutemen.
