 To publish a new release, project maintainers should commit new assets to the `cdn/` directory and push to the `main` branch. The jQuery CDN (code.jquery.com) and releases site (releases.jquery.com) will both automatically rebuild.
 
-## jQuery CDN
-
-The jQuery CDN assets are served from a static file server (Nginx), provisioned through Docker.
-
-Prerequisites:
-* Docker (see [Docker CE for Linux](https://docs.docker.com/install/#server), [Docker for Mac](https://hub.docker.com/editions/community/docker-ce-desktop-mac), or [Docker for Windows](https://docs.docker.com/docker-for-windows/install/)).
-* Git.
-
-### Local development
-
-**Build the image**:
-
-Build the image, by running the following in a clone of this repo:
-
-```
-docker build -t codeorigin ./
-```
-
-**Test the container**:
-
-1. Start a container, exposing port 80:
-   ```
-   docker run --rm -p 4000:80/tcp codeorigin
-   ```
-1. The site is now running at <http://localhost:4000/jquery-3.0.0.js>.
-   To stop the container, press `ctrl+c`
-
-**Inspect the container**:
-
-Run it with a shell entrypoint and set interactive/tty mode by adding the parameters `-i -t --entrypoint /bin/sh`.
-Note that when inspecting the container, nginx will not be started.
-
-```
-docker run --rm -p 4000:80/tcp -it --entrypoint /bin/sh codeorigin
-
-# /docker-entrypoint.d/20-envsubst-on-templates.sh 3>&1
-...
-# cat /etc/nginx/conf.d/default.conf
-...
-```
-
-**Debug nginx**:
-
-In `cfg/default.conf`, change `error_log … crit` to `error_log … debug` and then build+run as usual.
-
-### Production deployment
-
-1. At a hosting platform of your choosing, build or pull the container.
-1. Finally, configure the CDN to use the container address as its origin, with special handling to augment origin pulls with a `Host: code.jquery.com` header.
