Upgrading from 3.x to 4.x

Upgrading from an older version of Jekyll? A few things have changed in Jekyll 4 that you’ll want to know about.

Before we dive in, you need to have at least Ruby 2.3.0 installed. Run the following in your terminal to check

ruby -v

If you’re using Ruby >= 2.3.0, go ahead and fetch the latest version of Jekyll:

gem update jekyll
