One of my goals with the redesign was to improve the portability of my site's stack. It's now pretty simple getting it to work on a fresh Linux install. For example, on Debian Jessie, install the following packages:

sudo apt-get install ruby ruby-dev git imagemagick libmagickwand-dev pandoc pandoc-citeproc

then install bundler

sudo gem install bundler

Next, clone the git repo and navigate into the directory

git clone https://github.com/tlnagy/tnsite.git
cd tnsite

and run bundler to install all ruby dependencies

bundle

Finally, build and serve the website with Jekyll:

jekyll serve -wi
