+We can use `dvc get --show-url` to get the actual location of the resulting model file from our
+[get started example repo](https://github.com/iterative/example-get-started), a
+<abbr>DVC project</abbr> hosted on GitHub:
+
+```dvc
+$ dvc get https://github.com/iterative/example-get-started model.pkl --show-url
