On your ArtStation website, you can create a static page. In your Website Builder, click on "Pages" to access the Page Management section.
From there, you can create a new page.
Pages are comprised of content blocks. You can add content blocks such as text, images, etc.
Once you have published a page, you can add it to the top menu of your website, or on your home page by going to your Theme Customizer and adding it there.
