+# Contributing to CHRE
+
+It is encouraged that vendors implementing CHRE for their platforms contribute
+their code back to the open source project when possible as this will help
+provide more reference code for others and give the CHRE team better insight
+into the various use cases of users of the project.
+
+Anyone can upload patches to the Android Open Source Project (AOSP) and have
+the CHRE team review them using [these
+instructions](https://source.android.com/setup/contribute/submit-patches).
