Here is the official Field Service manual:

If you don't want to install the Demo Data Package you can follow the steps below.
Setup tasks I'm usually doing for testing/demonstration purposes include:
1. Connect to Maps: go to Resouce Scheduling => Settings => Administration. Set the field "Connect to Maps" to Yes.
2. Enable Bing Maps on forms: go to "Dynamics 365 - custom" => Settings => Administration => System Settings. Set "Show Bing Maps on forms" to Yes. Click OK.
3. Create a new Account record where you also enter an address and make sure that the "Latitude" and "Longitude" fields get populated by the system (a popup should appear asking you to confirm the address). Save.
4. Create an Organisation Unit: go to Resouce Scheduling => Settings => Organisation Unit. Click on "+ New". Provide a Name, i.e. "Site xy", click on Tab "Scheduling" provide "Latitude" and "Longitude" which are close to the geo data of the newly created account. (To get this geo data for the Organisation Unit you could have created a second account record and copy & paste the Long./Lat. from there). Save the new Org Unit.
5. Create a new Resource: go to Resouces => Resources: Click on "+ New". Choose your User in the field "User". Go to the tab "Scheduling". Change Start Location and End Location to "Organisation Unit Address". Choose the newly created Organisation Unit in the field "Organisation Unit". Save.
6. Create a Price List: go to Field Service => Settings => Price Lists. Click "+ New". Only provide a Name for the Price List, i.e. "Standard Price List (Euro). That's enough for your demo case. Save.
7. Create a Work Order Type: go to Field Service => Settings => Work Order Types. Click "+ New". Provide a name, i.e. "Repair". Set the field "Taxable" to No. Choose the newly created Price List into the field "Price List".
You now can create your first Work Order: Go to Field Service => Service => Work Orders. Click on "+ New". Choose the newly created Account into the field "Service Account". Choose the newly created Work Order Type into the field "Work Order Type". Save.
Now go to to Field Service => Service => Schedule Board. You should be able to see your newly created Resource at the Board. Now, at the bottom of the Resource list, open the slider "Booking Requirements", there click on the Tab "Unscheduled Work Orders". On the left of the Resource list open the slider "Filter & Map View", there click on "Map View".
As soon as you highlight a Work Order in the "Unscheduled Work Order" List at the bottom, the map on the left should be zooming to the location of the highlighted Work Order.
You can now Drag & Drop the Pin of the Work Order from the Map to your Resouce in the Resource list at an appropriate time window. Or you can darg'n'drop the Work Order directly from the list at the bottom onto the Resource row.
Of course if you're completly new to Field Service it might be reasonable to also take a look at the demo data to get an idea for some of the examples provided there.
However I don't use demo data very much when I set up an new trial and only want to test certain scenarios.
