+# Binder for Trusty
+
+This is the Trusty port of the libbinder library.
+To build it, take the following steps:
+
+* Check out copies of the Trusty and AOSP repositories.
+* Apply the patches from the `trusty_binder` topic on both repositories.
+* Build Trusty normally using `build.py`.
+* Run the sample AIDL test for Trusty:
+  ```shell
+  $ ./build-root/.../run --headless --boot-test com.android.trusty.aidl.test
+  ```
+
+To run the Android-Trusty IPC test, do the following:
+
+* Build AOSP for the `qemu_trusty_arm64-userdebug` target:
+  ```shell
+  $ lunch qemu_trusty_arm64-userdebug
+  $ m
+  ```
+* In the Trusty directory, run the emulator with the newly built Android:
+  ```shell
+  $ ./build-root/.../run --android /path/to/aosp
+  ```
+* Using either `adb` or the shell inside the emulator itself, run the Trusty
+  Binder test as root:
+  ```shell
+  # /data/nativetest64/vendor/trusty_binder_test/trusty_binder_test
+  ```
+
+## Running the AIDL compiler
+For now, you will need to run the AIDL compiler manually to generate the C++
+source code for Trusty clients and services. The general syntax is:
+```shell
+$ aidl --lang=cpp -o <output directory> -h <output header directory> <AIDL files...>
+```
+
+The compiler will emit some `.cpp` files in the output directory and their
+corresponding `.h` files in the header directory.
