  +OpenThread uses and enforces the [OpenThread Coding Conventions and Style](STYLE_GUIDE.md) on all code, except for code located in [third_party](third_party). Use the `make pretty` and `make pretty-check` targets to automatically reformat code and check for code-style compliance, respectively. OpenThread currently requires [clang-format v6.0.0](http://releases.llvm.org/download.html#6.0.0) for `make pretty` and `make pretty-check`.
  As part of the cleanup process, you should also run `make pretty-check` to ensure that your code passes the baseline code style checks.
