 ## Installing and running the app
 
-* **Windows only**
-
-  On Windows you will need to manually download and install the wheel for libxml2.
-
-  From the [Unofficial Windows Binaries for Python Extension Packages page](https://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml) download lxml 4.9 for your version of Python and OS version. For example, if you are using 64-bit Windows with Python 3.11, download `lxml‑4.9.0‑cp311‑cp311‑win_amd64.whl`.
-
-  Install this using `pip`:
-
-  ```bash
-  pip install <path to download>\<file name>
-  ```
-
-  For example, if you are using 64-bit Windows with Python 3.11 and downloaded it to `c:\temp`, you would run:
-
-  ```bash
-  pip install c:\temp\lxml‑4.9.0‑cp311‑cp311‑win_amd64.whl
-  ```
-
-  You do not need to do this step if you are on Linux or macOS.
-
 * Install the CounterFit app:
 
     ```sh
