+#rails4windocker: Ruby on Rails on Docker for Windows
 
 This creates a Ruby on Rails development environment that is shared between your Windows 10 desktop and a Docker container running CentOS. Use the bash command-line to administer Rails in a stable Linux environment, while accessing your code through Windows Explorer and the text editor of your choice.
 
 This is a development and testing environment. Don't run it in production - its not secure.

+Things to know:
+
+* The CentOS install running in the Docker should have enough features to run some basic gems, but if you need more tools installed under that environment, use "yum install <tool>" at the bash prompt.
+* Keep in mind that your environment will forget these tools after the Docker image resets upon exiting.
+* So, any yum installs that you want installed permanently should be added to the Dockerfile, then the docker image should be rebuilt using buildimage.bat.
