1. Download the Plugin
   Ghost has a WordPress plugin which allows you to move your content across easily. The plugin exports all posts, pages, tags, authors and images from your WordPress sites to Ghost.
2. Read the Preparation Guide
   Once the plugin is activated, you’ll see a small “preparation guide” which will show you what will be exported, and how you can prepare your WordPress content for Ghost.
3. Export the Ghost File
   When your content is ready to be exported, navigate to Export to Ghost in your Tools in the sidebar menu. The Download Ghost File button will start a download, ready for your content to import to Ghost.
4. Go to Labs in your Ghost Dashboard
   From there, log into your Ghost admin, navigate to the Labs view
5. Import your Content
   Choose the Import content option. Select your exported file, click Import and all your content will be imported and integrated to your Ghost site.
