* Is the contribution entirely your own work, or already licensed under an Apache License 2.0 compatible Open Source License? If not then we unfortunately cannot accept it.
* Is there documentation or examples that go with code contributions? `There are additional suggestions for writing good examples in the examples README <https://github.com/espressif/esp-idf/tree/master/examples>`_.
* If the contribution contains multiple commits, are they grouped together into logical changes (one major change per pull request)? Are any commits with names like "fixed typo" `squashed into previous commits <http://eli.thegreenplace.net/2014/02/19/squashing-github-pull-requests-into-a-single-commit/>`_?
Before a contribution can be accepted, you will need to sign our `Contributor Agreement <http://esp-idf.readthedocs.io/en/latest/contributing.html>`_. You will be prompted for this automatically as part of the Pull Request process.
