Upgrading

If you’re using the Ruby Gem version of the theme upgrading is fairly painless.

Simply run bundle update if you’re using Bundler (have a Gemfile) or gem update minimal-mistakes-jekyll if you’re not.

Use Git

If you want to get the most out of the Jekyll + GitHub Pages workflow, then you’ll need to utilize Git. To pull down theme updates you must first ensure there’s an upstream remote. If you forked the theme’s repo then you’re likely good to go.

To double check, run git remote -v and verify that you can fetch from origin https://github.com/mmistakes/minimal-mistakes.git.

To add it you can do the following:

$ git remote add upstream https://github.com/mmistakes/minimal-mistakes.git

Pull Down Updates

Now you can pull any commits made to theme’s master branch with:

$ git pull upstream master

Depending on the amount of customizations you’ve made after forking, there’s likely to be merge conflicts. Work through any conflicting files Git flags, staging the changes you wish to keep, and then commit them.

Update Files Manually

Another way of dealing with updates is downloading the theme — replacing your layouts, includes, and assets with the newer ones manually. To be sure that you don’t miss any changes it’s probably a good idea to review the theme’s commit history to see what’s changed since.

Here’s a quick checklist of the important folders/files you’ll want to be mindful of:

Name  
_layouts Replace all. Apply edits if you customized any layouts.
_includes Replace all. Apply edits if you customized any includes.
assets Replace all. Apply edits if you customized stylesheets or scripts.
_sass Replace all. Apply edits if you customized Sass partials.
_data/navigation.yml Safe to keep. Verify that there were no major structural changes or additions.
_data/ui-text.yml Safe to keep. Verify that there were no major structural changes or additions.
_config.yml Safe to keep. Verify that there were no major structural changes or additions.
