+#### Display information about currently signed-in user
+
+You can access a `currentUser` property in any template to get details about the current user. If you are using ember-data, this will deserialize the `/sessions/current` response (provided by the support gem) using a configurable model name (defaults to "user").
+
+For example, assuming you have a fullName & email property on your user model, you can say:
+
+```handlebars
+Signed in as: {{currentUser.fullName}} ({{currentUser.email}})
+```
