 #### Coding Conventions and Style
 
-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 `script/make-pretty` and `script/make-pretty check` to automatically reformat code and check for code-style compliance, respectively. OpenThread currently requires [clang-format v19](https://github.com/llvm/llvm-project/releases/tag/llvmorg-19.1.0) for C/C++ and [yapf v0.31.0](https://github.com/google/yapf) for Python.
