+# You'll then see the `print`ed logs of
+# the `main` function and, mixed in with them, all the logs of `f` as it is run
+# locally, then remotely, and then remotely and in parallel.
+#
+# That's all triggered by adding the [`@stub.local_entrypoint`](/docs/reference/modal.Stub#local_entrypoint) decorator on `main`,
+# which defines it as the function to start from locally when we invoke `modal run`.
+#
+# ## What just happened?
+#
+# When we called `.remote` on `f`, the function was executed
+# **in the cloud**, on Modal's infrastructure, not locally on our computer.
+#
+# In short, we took the function `f`, put it inside a container,
+# sent it the inputs, and streamed back the logs and outputs.
+#
+# ## But why does this matter?
+#
+# Try doing one of these things next to start seeing the full power of Modal!
+#
+# ### You can change the code and run it again
+#
+# For instance, change the `print` statement in the function `f`
+# to print `"spam"` and `"eggs"` instead and run the app again.
+# You'll see that that your new code is run with no extra work from you --
+# and it should even run faster!
+#
+# Modal's goal is to make running code in the cloud feel like you're
+# running code locally. That means no waiting for long image builds when you've just moved a comma,
+# no fiddling with container image pushes, and no context-switching to a web UI to inspect logs.
+#
+# ### You can map over more data
+#
+# Change the `map` range from `20` to some large number, like `1170`. You'll see
+# Modal create and run even more containers in parallel this time.
+#
+# And it'll happen lightning fast!
+#
+# ### You can run a more interesting function
+#
+# The function `f` is obviously silly and doesn't do much, but in its place
+# imagine something that matters to you, like:
+#
+# * Running [language model inference](/docs/examples/vllm_mixtral) or [fine-tuning](/docs/examples/slack-finetune)
+# * Manipulating [audio](/docs/examples/discord-musicgen) or [images](stable_diffusion_xl_turbo)
+# * [Collecting financial data](/docs/examples/fetch_stock_prices) to backtest a trading algorithm.
+#
+# Modal lets you parallelize that operation effortlessly by running hundreds or
+# thousands of containers in the cloud.
