This image is intended for developmental purposes as it sets up all of the OS and Ruby environment for you. All you need todo is complete the Txgh server configuration which includes authentication information for both Transifex and GitHub.
To enable easy configuration a mount point is set to '/tmp/txgh'. If this directory exists on the host, Docker will map it for you...otherwise you can always adjust it as needed.
Information can be found here for Txgh: https://github.com/transifex/txgh/blob/master/LICENSE
