 The GitHub build process is isolated from the local development environment, ensuring a clean and isolated build environment. This prevents any potential conflicts with local volumes.
 
+### CircleCi Oddities
+
+You'll notice that the build_github.sh script does not share volumes to inject the default.conf into nginx. This is because circleci does not allow volume sharing between the host and the docker executor. This is a limitation of the circleci platform, and not a limitation of docker.
+As such we copy the nginx file into the container after the build process and restart the nginx service.
+
+CircleCI is also not a huge fan of docker compose port forwarding, so we run the tests from inside their docker container to be able to access the ngninx service on the network.

 ## Once Built
 
 Once the container is up and running, you can hit `http://localhost:8089/` it `/` will route you to FE react project by default.
