-Contributions Guide
-===================
-
-We welcome contributions to the Arduino ESP32 project!
-
-How to Contribute
------------------
-
-Contributions to Arduino ESP32 - fixing bugs, adding features, adding documentation - are welcome. We accept contributions via `Github Pull Requests <https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/about-pull-requests>`_.
-
-Before Contributing
--------------------
-
-Before sending us a Pull Request, please consider this list of points:
-
-* Is the contribution entirely your own work, or already licensed under an LGPL 2.1 compatible Open Source License? If not then we unfortunately cannot accept it.
-
-* Is the code adequately commented for people to understand how it is structured?
-
-* Is there documentation or examples that go with code contributions? 
-
-* Are comments and documentation written in clear English, with no spelling or grammar errors?
-
-* Example contributions are also welcome.
-
-* 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 <https://eli.thegreenplace.net/2014/02/19/squashing-github-pull-requests-into-a-single-commit/>`_?
-
-* If you're unsure about any of these points, please open the Pull Request anyhow and then ask us for feedback.
-
-Pull Request Process
---------------------
-
-After you open the Pull Request, there will probably be some discussion in the comments field of the request itself.
-
-Once the Pull Request is ready to merge, it will first be merged into our internal git system for in-house automated testing.
-
-If this process passes, it will be merged onto the public github repository.
-
-Legal Part
-----------
-
-Before a contribution can be accepted, you will need to sign our :doc:`contributor-agreement`. You will be prompted for this automatically as part of the Pull Request process.

- *  Udp.cpp: Library to send/receive UDP packets.

- * NOTE: UDP is fast, but has some important limitations (thanks to Warren Gray for mentioning these)
- * 1) UDP does not guarantee the order in which assembled UDP packets are received. This
- * might not happen often in practice, but in larger network topologies, a UDP
- * packet can be received out of sequence.
- * 2) UDP does not guard against lost packets - so packets *can* disappear without the sender being
- * aware of it. Again, this may not be a concern in practice on small local networks.
