+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.

+Some locales have limited coverage and rely more heavily on the English locale as the source for features they currently do not have.
+However, in most cases, using a specific locale will be beneficial in the long term as specifying a locale reduces the time necessary for startup, which has a compounding effect on testing frameworks that reload the imports every execution.

+:::tip Note
+Using the first import statement will load every locale into memory.
+As such, start-up times and performance may be slow.
+Thus, by declaring a locale in the import, one can increase performance and reduce the time on start-up.
