-This is the documentation site for [`cal-itp/docker-python-web`](https://github.com/cal-itp/docker-python-web).
-
-`docker-python-web` is a base [Docker image](https://www.docker.com/) for Cal-ITP Python web applications.
-
-## Features
-
-- Base image `python:3.12-bookworm`
-- Image configured with non-`root` user (`calitp` by default)
-- `nginx` configured as a reverse proxy listening on container port `8000`
-- `gunicorn` configured as a WSGI application server, communicates with `nginx` over Unix socket
-- `gunicorn` default configuration location in `$GUNICORN_CONF`
-- `gettext` for use with web frameworks like Django
-- `WORKDIR` set to `/home/$USER/app`; `gunicorn` configuration in `/home/$USER/run`
-
-## Non-Features
-
-- Bring Your Own Web Framework
-  - see [`benefits`](https://github.com/cal-itp/benefits) for a `Django` example
-  - see [`eligibility-server`](https://github.com/cal-itp/eligibility-server) for a `Flask` example
-- Bring Your Own `CMD`: drop in to `bash` with the default `ENTRYPOINT`.
-
-## Usage
-
-Reference one of the `image:tag` from GitHub Container Registry in a `Dockerfile`. E.g. for the `main` branch:
-
-```dockerfile
-FROM ghcr.io/cal-itp/docker-python-web:main
-
-COPY my_app my_app
-
-CMD "nginx && python -m gunicorn -c $GUNICORN_CONF my_app.wsgi"
-```
-
-Or from the command line:
-
-```shell
-docker pull ghcr.io/cal-itp/docker-python-web:main
-```
-
-## Development
-
-Development for this repo is done within a Visual Studio Code [devcontainer](https://code.visualstudio.com/docs/remote/containers).
-
-!!! warning
-
-    You must build the base Docker image `cal-itp/docker-python-web:app` before running the devcontainer. In a terminal, run:
-    ```
-    docker compose build app
-    ```
-
-Then, with the [Remote - Containers](https://code.visualstudio.com/docs/remote/containers) extension enabled, open the folder containing this repository inside Visual Studio Code.
-
-The image you just built can be accessed from other (local) codebases via:
-
-```dockerfile
-FROM docker-python-web:app
-```
