To create a new page, click the New Page link in the control panel navigation. You will be take to the New Page form.
The page needs a Title. The title that you provide will be used for the <title> tag, and will be used by search engines when they list your page. It will also be used to generate a URL for the page (see later).
The page also needs a layout page. When you first run the site with the default Theme, the layout page is called _SiteLayout.cshtml and is the only option available for selection.
Having selected the layout page, the Layers dropdown is populated with all layers associated with the selected layout page. Layers are groups of pages that share widgets. You can read more about Layers in Managing Layers. When you select _SiteLayout.cshtml, the default layer is called Default, and will be applied whether you select it or not. The Default layer represents all pages that share SiteLayout.
If you want the page to act as the Home Page, tick the box.
This will remove the value from the Page Url input. Unticking the Home Page checkbox will result in the default Page Url value being reapplied. The value that appears in the Page Url input will be the URL at which the page can be reached. This can effectively be any unique value, but it defaults to the page's title with spaces replaced with dashes. The particular page that you are reading right now has had the default value prefixed with "tutorials/".
Content for the page is provided through a Rich Text Editor which enables HTML and allows you to apply formatting, include images, tables and so on.
If you want the page to appear in a menu, tick the Add To Menu box.
Then you can select one from the drop down (the default "main menu" will be the only one available until you add you own menus) and you can provide the text that should appear in the menu, as well as decide where in the menu the page should appear by providing a value for the Menu Order. Items appear in ascending order.
You can provide a Meta Description for the page. Best advice is to keep this to around 160 characters. It should describe the content or purpose of the page and is what search engines display in their search results pages.You can also provide Meta Keywords (although the general consensus is that most search engines ignore them).
Finally, you can choose to save the current version without publishing, publish the page now or schedule it to be published later - all depending on permissions.
If you choose Save, the page is saved as a draft. If you choose to publish now, the version will be saved with the current date and time as the publish date, which means that it will be live on your site instantly. If you choose to publish later, you will be prompted to specify the date and time that the page should become live on the site.
