_sass and _js are containing the source files. The css and js folders and their content are only contained in this repository to provide them for gh-pages. These tasks aren't included in the Jekyll build itself which is why setting up a development machine is recommended. See the instructions for Windows and Mac OS X below.
These are the full development instructions to get a development machine running under Microsoft Windows.
Get the Git binaries from https://git-scm.com/ or download GitHub Desktop from https://desktop.github.com/, then clone the repository to your local machine (e.g., C:\Users\[User]\Documents\GitHub\pie.fh-hagenberg.at).
Go to http://rubyinstaller.org/, download the latest installer for Ruby and run it.
Once Ruby is installed, install Jekyll as a Ruby gem via your Ruby enabled command prompt (Launch “Start command prompt with Ruby” in your start menu). Details here: http://jekyllrb.com/docs/installation/
To be able to compile SASS (and other things), Node.js needs to be installed. Go to https://nodejs.org/ and download the latest stable version and install. Mature and stable (usually older) is not required.
Open a Terminal window and go to the directory where you cloned the repository to (e.g., C:\Users\[User]\Documents\GitHub\pie.fh-hagenberg.at). Type in npm install to install all necessary dependencies.
The build workflow uses gulp. To start the server an all necessary tools, open a “Node.js command prompt” window, navigate to the cloned repository and enter gulp dev. This should start everything including your Jekyll server. To access the website go to http://localhost:4000/pie.fh-hagenberg.at.
Should the gulp command not succeed, you might have to install gulp globally again. Just type npm install –global gulp.

Get the Git binaries from https://git-scm.com/ or download GitHub Desktop from https://desktop.github.com/, then clone the repository to your local machine (e.g., /Documents/GitHub/pie.fh-hagenberg.at).
Use the Ruby Version Manager (RVM) to get the latest Ruby version installed. Go to http://rvm.io/ and follow the installation instructions on the front page. Provide the flag --ruby to install ruby together with RVM in one go.
Once Ruby is installed, install Jekyll as a Ruby gem via Terminal. Details here: http://jekyllrb.com/docs/installation/

gulp dev: Development mode that watches the directory for changes.gulp build: Build mode that creates a current build of the website in the_sitedirectory.gulp test: Test mode that only runs eslint and stylelint to check for errors.
