+* types.hal (structure definitions)
+
+Note that the <i>1.2</i> HAL is supplemental to the <i>1.0</i> HAL - not a replacement.
+
+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/wifi/</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>.
