This tutorial assumes you've already logged in to WordPress, and will show you how to update your WordPress installation.
First, you can see which version of WordPress you're running right here.
Click the Updates link in the left margin.
This is where you go to update your WordPress installation. You should click Check Again to make sure your
installation is up to date. Our version of WordPress is up to date...
If there's a problem and WordPress needs to be re-installed, you can do so here.
You can also update your plugins, themes, and translations from this page too.
Once the installation is complete, you'll see this welcome screen.
