To install this beautiful shiny new version from scratch visit the download section to the right of the homepage and grab a copy. Then follow the directions in the “Read Me” file.
If you already have WordPress installed, update it to the latest version in the dashboard if you haven’t already. Then go into the General Settings and Change your “Site Language” to “English (Canada)”. That’s it, you’re done, WordPress in the back will download the language files for it and every theme and plugin you have that is hosted on WordPress.org.
