Requirements ============ You will need the following things before starting this tutorial: - An Android phone that can run Android OS 5.1+. Any feature phone made in or after 2012 should work. A tablet would probably also work, provided it has a camera. - A computer capable of running the `Google Chrome `_ web browser (Firefox supposedly works, but we think Chrome works better) - `Google `_ account (you'll use this to sign in to your App Inventor account) - `PythonAnywhere `_ account (this is a free service that allows you to set up the server software that we use during this tutorial) Once you have all your accounts set up, go to the :doc:`installation instructions `. If you don't have a compatible Android device, don't despair! You can also develop entirely on your computer, using an emulator. Please see the :doc:`emulator installation instructions `.
