+# HomeSpan Categories
+
+Every HomeSpan device must be assigned a HomeKit Accessory Category. HomeSpan implements these categories as C++ Classes with names that exactly match the spelling and capitalization specified by Apple in Section 13 of [HAP-R2](https://developer.apple.com/support/homekit-accessory-protocol/), but without any spaces.  HomeSpan Accessory Categories are defined in HomeSpan's `Category` namespace.  For example, HomeSpan defines the *Garage Door Openers* Category (HAP Category 4) as `Category::GarageDoorOpeners`, which could be used when initializing HomeSpan as follows:
+
+```C++
+homeSpan.begin(Category::GarageDoorOpeners,"Acme Garage Door Lifts");
+```
+The table below provides a list of all HomeSpan Categories.
