+The above code indicates a basic usage of Faker.
+The point of interest is the import statements at the top.
+The first import indicates how one can import the entirety of Faker, which includes every local, while the commented-out import showcases how to import only a single local.
+In most situations, importing a single local is preferable for performance because some testing frameworks reload imports for every test file, which causes startup latencies to add up quickly.
+Thus, limiting the import to a single locale can speed up startup times.
