Getting started with WordPress
There are two types of WordPress websites: Wordpress.com and Wordpress.org
Wordpress.com requires that you use one of the themes available on their site. You will not be able to use a theme purchased on Creative Market on Wordpress.com. Creative Market sells Wordpress.org themes, which you host yourself. Here are some helpful resources on our blog that will get you started:
For your new WordPress.org theme, the key thing to remember is that you'll want to find your own host and your own domain to operate a WordPress.org site. The major benefit to this is that you can install custom themes from third-party sites (like ours), build your own PHP and CSS, and not have as many limitations to customizing your blog.
