The network should be transparent to applications. When network and application problems do occur it should be easy to determine the source of the problem.

Contributing to Envoy is fun and modern C++ is a lot less scary than you might think if you don't have prior experience. To get started:
- [Contributing guide](CONTRIBUTING.md)
- Beginner issues
- [Build/test quick start using docker](ci#building-and-running-tests-as-a-developer)
- [Developer guide](DEVELOPER.md)
- Consider installing the Envoy development support toolchain, which helps automate parts of the development process, particularly those involving code review.
- Please make sure that you let us know if you are working on an issue so we don't duplicate work!
