A Dockerfile in guacamole-manual will simplify setup for developers and others who wish to contribute to the user manual. Installing all of the dependencies needed to build for all targets is time consuming and error prone. Using Docker, a contributor need only have git, a reasonable editor, and Docker installed in order to contribute to the user manual.
The Dockerfile should use a two-stage build. The first stage installs the build dependencies and then runs make to build the documentation. The second stage copies the artifacts from the build into a container image based on Apache httpd that can be used to view the documentation using a web browser.
