- * and be blocked until it has completed or a timeout condition has been
- * reached, or poll the result periodically. Both poll and wait* may safely be
- * called concurrently, even on the same event. When the server thread has
- * completed, it should immediately call "notify" to indicate the corresponding
- * output has been produced and awaken any client threads waiting on the event.
- *
- * This class exists to enable synchronization across HIDL. When synchronization
- * is only required in the same process, consider using std::future, std::mutex,

+# Wi-Fi Aware (NAN) HAL API Usage
+
+The Wi-Fi Aware (NAN) HAL API is defined in (<i>hardware/interfaces/wifi/\<version\>/</i>):
+
+* IWifiNanIface.hal
+* IWifiNanIfaceEventCallback.hal
+* types.hal (structure definitions)
+
+The Wi-Fi Aware (NAN) HAL API surface is very large - only a subset is used from the framework.
+
+Understanding of the HAL API subset which is actively used by the Android framework can be deduced
+by reviewing framework code, specifically (<i>frameworks/opt/net/wif/</i>):
+
+* WifiAwareNativeApi.java
+* WifiAwareNativeCallback.java
+
+The above framework files determine the API usage - and should be consulted as the authoritative
+reference. Please consult the primary HAL file for documentation - they will not be replicated
+in this document. APIs which are in the HAL but are not listed in this README file are not used by
+the framework.
+
+Note: the HAL API is translated to the legacy HAL API (<i>wifi_nan.h</i>). This README file covers
+the new HAL API only. To understand the mapping between new and legacy HALs please consult
+<i>hardware/interfaces/wifi/\<version\>/default/hidl_struct_util.cpp</i>.
