 Fetching a Token and Creating a Client
 --------------------------------------
 
-``schwab-py`` provides an easy implementation of the client-side login flow in 
-the ``auth`` package. It uses a `selenium 
-<https://selenium-python.readthedocs.io/>`__ webdriver to open the Schwab
-authentication URL, take your login credentials, catch the post-login redirect, 
-and fetch a reusable token. It returns a fully-configured :ref:`client`, ready 
-to send API calls. It also handles token refreshing, and writes updated tokens 
-to the token file.
-
-These functions are webdriver-agnostic, meaning you can use whatever 
-webdriver-supported browser you have available on your system. You can find 
-information about available webdriver on the `Selenium documentation
-<https://www.selenium.dev/documentation/en/getting_started_with_webdriver/
-browsers/>`__.

-When creating a ``schwab-py`` token using a webrowser-based method like 
-:func:`~schwab.auth.client_from_login_flow` or :func:`~schwab.auth.easy_client`, 
-the library must control the browser using `selenium 
-<https://selenium-python.readthedocs.io/>`__. This is a Python library that 
-sends commands to the browser to perform operations like load pages, inject 
-synthetic clicks, enter text, and so on. The component which is used to send 
-these commands is called a *driver*. 
-
-Drivers are generally not part of the standard web browser installation, meaning 
-you must install them manually. If you're seeing this or a similar message, you 
-probably haven't installed the appropriate webdriver. Drivers are 
-available for most of the common web browsers, including `Chrome

-<https://github.com/mozilla/geckodriver/releases>`__, and `Safari 
-<https://developer.apple.com/documentation/webkit/testing_with_webdriver_in_safari>`__.  
-Make sure you've installed the driver *before* attempting to create a token

-What If I Can't Use a Browser?
-++++++++++++++++++++++++++++++
-
-Launching a browser can be inconvenient in some situations, most notably in 
-containerized applications running on a cloud provider. ``schwab-py`` supports 
-two alternatives to creating tokens by opening a web browser. 
-
-Firstly, the :ref:`manual login flow<manual_login>` flow allows you to go 
-through the login flow on a different machine than the one on which 
-``schwab-py`` is running. Instead of starting the web browser and automatically 
-opening the relevant URLs, this flow allows you to manually copy-paste around 
-the URLs. It's a little more cumbersome, but it has no dependency on selenium.
-
-Alterately, you can take advantage of the fact that token files are portable. 
-Once you create a token on one machine, such as one where you can open a web 
-browser, you can easily copy that token file to another machine, such as your 
-application in the cloud. However, make sure you don't use the same token on 
-two machines. It is recommended to delete the token created on the 
-browser-capable machine as soon as it is copied to its destination.
