+# RemoteAuth Mainline Module
+
+This directory contains code for the RemoteAuth module.
+
+## Directory Structure
+
+`framework`
+ - Contains client side APIs and AIDL files.
+
+`jni`
+ - JNI wrapper for invoking Android APIs from native code.
+
+`native`
+ - Native code implementation for RemoteAuth module services.
+
+`service`
+ - Server side implementation for RemoteAuth module services.
+
+`tests`
+ - Unit/Multi devices tests for RemoteAuth module (both Java and native code).
