To use feeds to generate pages on your site you will need to first create a page template using mustache style tokens as placeholders for feed content. For example if you make the title of a block {{title}} that token will be replaced with the title from the feed.
When your template is created, edit the settings for the feed that you want to publish as pages on your site. In the right panel of the feed editor (for the feed itself, not an individual feed item) you can enable the checkbox to publish with site content and select which section of your site and which template to publish into. The URL of the page will be determined by the URL set on each individual feed item. If no URL is set the URL will be generated as a URL friendly (and unique) reformatting of the feed item title. When editing an individual feed item that is part of a feed to be published with the site there will be an option to preview the feed item in the template for your review.
Here are the basic elements of a feed item to populate a template with:
- {{title}}
- {{body}}
- {{date}}
- {{url}}
- {{media}}
Any custom fields added to the feed will also have their tokens replace with the matching field. For example if you add a custom field to the feed with the field "author" you will be able to use it in your page template with the token {{author}}
Here is an example screenshot of a template that will be populated by a feed and published.
