Let's review what you learned in this course!
You should now have a good overview of the process for building multi-language sites with Craft CMS.
First, you define your sites with their respective languages, and optionally organize them into groups.
Next, you make your sections available on those sites as needed, and choose how content is propagated in each of your sections. For propagated content, you also define which fields are translatable, and which fields share their content between some or all sites.
Finally, in your templates, you can pull in content from other sites using element queries All of the tiny pieces of interface text can be translated using static message translations.
