By default the homepage will look like a blog (this is how WordPress is intended to work). If you have imported one of the Theme Demos select the desired page or if you want a custom homepage you can create it using the salient page builder then go to Settings > Reading and you can define your homepage here. 

Make sure you have created and published your homepage page prior. If you don’t have any pages or all your pages are currently drafts then you won’t be able to see the settings in the screenshot below.
