Now that WordPress is installed, it’s time to set up your theme.
You can move all the content from your current site to your new self-hosted WordPress site, but themes and widgets cannot be moved, so you’ll want to set up a new theme on your site.
There are many places to find WordPress themes — one great option is to browse and download one from the WordPress.org theme directory.
If you’re happy with the theme you’re currently using on WordPress.com, you may be able to use it for your new site as well.
To search for your WordPress.com theme, use the action bar in the bottom right when visiting your site and click the Get Theme link. On the theme’s page, you can scroll down to the bottom of the Overview tab and download the theme to use with your self-hosted site.
If you are unfamiliar with how to install a theme in WordPress, the Using Themes page on WordPress.org has the instructions.
Once your theme is installed and activated you’ll need to setup the widgets for the site as well. You can find more information about working with them on the WordPress.org widgets page.
