-# Update me once in a while: https://github.com/github/pages-gem/releases
-# Please ensure, before upgrading, that this version exists as a tag in starefossen/github-pages here:
-# https://hub.docker.com/r/starefossen/github-pages/tags/
-#
-# Fresh install?
-#
-# Windows:
-# Install Ruby 2.3.3 x64 and download the Development Kit for 64-bit:
-# https://rubyinstaller.org/downloads/
-#
-# Run this to install devkit after extracting:
-# ruby <path_to_devkit>/dk.rb init
-# ruby <path_to_devkit>/dk.rb install
-#
-# then:
-# gem install bundler
-# bundle install
-#
-# Mac/Linux:
-# Install Ruby 2.3.x and then:
-# gem install bundler
-# bundle install
-#
-# ---------------------
-# Upgrading? Probably best to reset your environment:
-#
-# Remove all gems:
-# gem uninstall -aIx
-#
-# (If Windows, do the dk.rb bits above, then go to the next step below)
-
-# Install anew:
-# gem install bundler
-# bundle install
-
-# This only affects interactive builds (local build, Netlify) and not the
-# live site deploy, which uses the Dockerfiles found in the publish-tools
-# branch.
