Insert new pages

Good morning,
If I want to add new pages or new content to the sides of the site as I do?

I have added a section in this menu but then how do I display?

If you mean adding a link to a topic in a menu, you'd do something like:

<a href="@Url.RouteUrl("Topic", new { SystemName = "MySystemName" })">@T("MySystemNameInLocalisation")</a>

...where MySystemName is the name of the topic you've added and MySystemNameInLocalisation is the key/name of the localisation string.
