-# Getting started
-
-Follow these instructions to get started as a developer for this project.
-
-1.  Install Python 3.10 for Windows.
-
-    You can download an installer from here for example.
-    [python.org/downloads/release/python-31011/](https://www.python.org/downloads/release/python-31011/)
-
-    There isn't a mediapipe for 3.12 Python, which is the latest at time of
-    writing.
-
-2.  Check the Python version is installed, on the path, and so on.
-
-    If you run this command you should get this output.
-
-        > python --version
-        Python 3.10.11
-
-    If you don't then restart Powershell or VSCode or VSCodium, or the whole
-    machine. Or check the PATH environment variable.
-
-3.  Create a Python virtual environment (venv).
-
-    Python venv is now the best practice for programs that require PIP modules.
-
-    Run commands like these to create the venv in a sub-directory also named
-    `venv`. The repository is already configured to ignore that sub-directory.
-
-        cd /path/where/you/cloned/FaceCommander
-        python -m venv venv
-
-    Going forwards, you will run Python like this.  
-    `./venv/Scripts/python.exe` ... other command line options ...
-
-4.  Install the required PIP modules.
-
-    Run commands like these to update PIP and then install the required modules.
-
-        cd /path/where/you/cloned/FaceCommander
-        ./venv/Scripts/python.exe -m pip install --upgrade pip
-        ./venv/Scripts/python.exe -m pip install -r ./requirements.txt
-
-5.  Run the program.
-
-    Run commands like this.
-
-        cd /path/where/you/cloned/FaceCommander
-        ./venv/Scripts/python.exe face_commander.py
-
-The program should start. Its print logging should appear in the terminal or
-Powershell session.
