Setup dev env

GitHub Pages does NOT support the latest Ruby nor the latest Jekyll not every Jekyll gem. Here is a list of the gems and their versions, which are suppoerted on GitHub Pages: https://pages.github.com/versions/

• Install Ruby (last I checked GitHub Pages is using Ruby 2.7.1). Last time it was sudo apt-get install ruby-full, but check here: https://www.ruby-lang.org/en/documentation/installation/#apt Don't forget to run source ~/.bashrc to load the new $PATH values
• Install Bundler (a Ruby gem): gem install bundler
• Install all the gems in the Gemfile: bundle install
• Run the server bundle exec jekyll serve --future

Jekyll is a Ruby's gem. All the gem's you will use to run your site have to be listed in the Gemfile.

Updating gems

Every so often run bundle update --all and then commit the new generated Gemfile.lock.
