# 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).
