+# 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).
+
+## IDE setup
+
+### AIDEGen
+
+AIDEGen is deprecated, prefer ASfP [go/asfp](http://go/asfp)
+```sh
+$ source build/envsetup.sh && lunch <TARGET>
+$ cd packages/modules/Connectivity
+$ aidegen .
+# This will launch Intellij project for RemoteAuth module.
+```
+
+### ASfP
+
+See full instructions for ASfP at [go/asfp-getting-started](http://go/asfp-getting-started)
+
+## Build and Install
+
+```sh
+$ source build/envsetup.sh && lunch <TARGET>
+$ m com.google.android.tethering deapexer
+$ $ANDROID_BUILD_TOP/out/host/linux-x86/bin/deapexer decompress --input \
+    ${ANDROID_PRODUCT_OUT}/system/apex/com.google.android.tethering.capex \
