Rather than download the source files from GitHub, you can also download the framework for the USB/SD memory as a .zip file from here:
Download the .zip file and expand it in the top level directory of your memory device, or in a working directory on your PC.
Then if you click on the index.html file you will get the VT-Rachel home page with links to each of the content modules.
If you look in the 'modules' directory you will see a directory for each module of content, but they will not have the actual content files in them.
You can download the content modules that you want from the OER2G0.org web site (http://oer2go.org/
) and place the contents into the respective directory.
The OER2Go site offers several different download options. The rsync option is recommended if you are running a Linux style operating system like Ubuntu on your PC as it is a robust download mechanism that can be easily resumed if something breaks along the way.
Other alternatives are Zip file over FTP or Zip file via Web.
Once you download the content files, unpack the zip file and copy the files into the "en-catdogbooks" directory.
Then you should be able to link to the content from the VT-Rachel home page.
Repeat the process for other content modules that you want to get.
Be aware that the content downloads are quite large eg the Khan Academy on a Stick (KAOS) is 16GB.
Downloads of this size can be problematic, hence the recommendation to use rsync.
I hope this helps.
