This is where the magic happens. The place that will lead you to downloading and installing Umbraco CMS. Free of charge, of course.
It is waiting for you on Umbraco's friendly community website called Our.
Our is also where you'll find the Umbraco installation guide as well as the official Umbraco documentation. So, pretty much all you need to start and to start right:
Perhaps what you need is an Umbraco update? You can sort that out on Our as well. That's where you'll find the releases page containing the earlier and the newest releases.
It's an option you should use if you need to upgrade to an earlier version or want to install a specific version.
Pssst... before you go, we got one last tip for you. You can witness the latest Umbraco version in action by taking a 14-day Umbraco Cloud trial.
It takes around 2 minutes to start and then it's completely free to play around for 2 weeks (no credit card needed). Enjoy!
