 When the compilation and tests succeed, you will be dropped in to a shell environment within the container. This can be useful to build other things within the environment. Additional tests can be run as well as debugging of code.
 
+# Docker Hub
+These images are also uploaded to the wolfSSL's [Docker Hub page](https://hub.docker.com/orgs/wolfssl/repositories). There is a convenience script here `buildAndPush.sh` that will create the appropriate containers and push them to the repo.

 # FAQ
 ## permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock
 You need to be added to the `docker` group to run Docker containers. Run `sudo usermod -aG docker $USER`. You may need to restart the Docker daemon.
 
 ## Unable to access symlinked files outside of WolfSSL
 The volume mounted in the Docker container needs to have all files that your compilation will need. To solve this, you have a couple options:
 1. Change the `WOLFSSL_DIR` variable in the `run.sh` to one higher up (by adding `/..` to the path). Then update the `docker build` to include the correct path to the Dockerfile and the `docker run` argument to the working directory (`-w`) to the WolfSSL source directory
-2. Move the external repository to within the WolfSSL directory. For example create an `external` folder which has your files. This route may have complications when stashing Git work.
