# Getting our app ready for Render
We need to add
gunicorn to our
requirements.txt file before we deploy to Render.
You won't be able to run
gunicorn in Windows, but you can install it. In other platforms, you should be able to run
gunicorn. Either way, you'll be using
flask run to run your app locally most of the time. We'll only use
gunicorn in Render.com for performance benefits.
