Stay Up to Date

We recommend you update Jekyll as often as possible to benefit from the latest bug fixes.

If you followed our setup recommendations and installed Bundler, run bundle update jekyll or simply bundle update and all your gems will update to the latest versions.

If you don’t have Bundler installed, run gem update jekyll.

The procedure is similar if you use the github-pages gem.
