zlib1g-dev

We recommend installing gems to a (hidden) directory in your home folder:

echo '' >> ~/.bashrc
echo '# Install Ruby Gems to ~/.gems' >> ~/.bashrc
echo 'export GEM_HOME="$HOME/.gems"' >> ~/.bashrc
echo 'export PATH="$HOME/.gems/bin:$PATH"' >> ~/.bashrc
echo '' >> ~/.bashrc
source ~/.bashrc

Install jekyll and bundler:

gem install jekyll bundler

Install gems:

bundle install

Build and serve locally with:

bundle exec jekyll serve --host 0.0.0.0

The site should now be available at http:https://0.0.0.0:4000/ on your local machine, and your local machine's IP address on your network—great for testing on mobile OSes.
