The source for the Scribble Language Guide uses asciidoc format, and is converted to a web page (and PDF) using gitbook.
First step is to fork the github repository and clone it onto your local machine.
git clone [email protected]:<your-username>/scribble-language-guide.git
To enable changes made locally to be checked, before being committed back to the git repository, you will need to install the gitbook tools.
Once installed, you will be able to open a command window in the root folder of the scribble language guide repo (clone) and type:
gitbook serve
This will watch the repository for changes, and present them as a web page located at: http://localhost:4000
