+property of `<mat-datepicker>` to `year`. In year view the user will see all months of the year and
 then proceed to month view after choosing a month.
 
 The month or year that the calendar opens to is determined by first checking if any date is

 open to the month or year containing today's date. This behavior can be overridden by using the

+`startAt` property of `<mat-datepicker>`. In this case the calendar will open to the month or year
 containing the `startAt` date.
 
 <!-- example(datepicker-start-view) -->
 
+### Setting the selected date
+
+The type of values that the datepicker expects actually depends on the particular `DateAdapter` that
+you're using in your app. For example, when using the `NativeDateAdapter` the datepicker expects
+`Date` objects, and when using the `MomentDateAdapter` it expects `Moment` objects. You can also
+create your own `DateAdapter` that works with whatever date type you want. (For more information
+about this, see the section on
+[choosing a date implementation](#choosing-a-date-implementation-and-date-format-settings)).
+
+Depending on the `DateAdapter` you're using, the datepicker may automatically deserialize certain
+date formats for you as well. For example, both the `NativeDateAdapter` and `MomentDateAdapter`
+allow [ISO 8601](https://tools.ietf.org/html/rfc3339) strings to be passed to the datepicker and
+automatically converted to the proper object type. This can be convenient when binding data directly
+from your backend to the datepicker. However, when possible, you should pass the appropriate object
+type. The datepicker will not accept date strings formatted in user format such as `"1/2/2017"` as
+this is ambiguous and will mean different things depending on the locale of the browser running the
+code.
+
+As with other types of `<input>`, the datepicker works with `@angular/forms` directives such as
+`formGroup`, `formControl`, `ngModel`, etc.

 ### Date validation

+
+### Disabling parts of the datepicker
+
+As with any standard `<input>`, it is possible to disable the datepicker input by adding the
+`disabled` property. By default, the `<mat-datepicker>` and `<mat-datepicker-toggle>` will inherit
+their disabled state from the `<input>`, but this can be overridden by setting the `disabled`

+but allow selection via the calendar or vice-versa.

 ### Touch UI mode

 The datepicker normally opens as a popup under the input. However this is not ideal for touch
 devices that don't have as much screen real estate and need bigger click targets. For this reason

  3. The message strings used in the datepicker's UI.

 #### Choosing a date implementation and date format settings
+
 The datepicker was built to be date implementation agnostic. This means that it can be made to work
 with a variety of different date implementations. However it also means that developers need to make
 sure to provide the appropriate pieces for the datepicker to work with their chosen implementation.
