Fixed a typographical error on line 246 - " we just map port 80 on the host to port 80 in the container" should be " we just map port 4000 on the host to port 80 in the container"
In the docker-compose file, the ports sections maps host port 4000 to container port 80, so if we want to see our app in a browser we should check on port 4000.
Proxy settings titles was placed in the DNS misconfiguration part, and the DNS settings title was placed in the proxy configuration part. This changes moves the places of the titles so that they both present the section they intend to.
The host port was set to 80, which was both inconsistent with the previous tutorial and also causing issues when following the tutorial on Windows.
For reference, here is the error when attempting to run a container on port 80:
C:\Program Files\Docker\Docker\Resources\bin\docker.exe: Error response from daemon: driver failed programming external connectivity on endpoint focused_euler (079893ea98df78bf7043f86072263317be106cbb7f4a3fcde23c2ef19ad39a01): Error starting userland proxy: Bind for 0.0.0.0:80: unexpected error Permission denied.

I had certificates issues when the pip command was run:
There was a problem confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:661)
Using the pip like this solved the issue:
RUN pip install --trusted-host pypi.python.org -r requirements.txt
