Step 0: Creating The Folders
It is recommended to install your Flask application within a virtualenv. Please read the :ref:`installation` section to set up your environment.
Now that you have installed Flask, you will need to create the folders required for this tutorial. Your directory structure will look like this:
/flaskr /flaskr /static /templates
The application will be installed and run as Python package. This is the
recommended way to install and run Flask applications. You will see exactly
how to run
flaskr later on in this tutorial.
For now go ahead and create the applications directory structure. In the next few steps you will be creating the database schema as well as the main module.
For now you should continue with :ref:`tutorial-schema`.
