Home Page

First start by creating the new page, then go to Settings > Reading and change the “Front page displays” option to A static page and select your new home page from the drop down list.

If you don’t want a blog page at all you can leave the “Posts page” as it currently is.
If you do want one you’ll need to create a blank page just enter the title (most likely “Blog”) and select that new page from the Posts pagedropdown.
