 Coding Guidelines
 =================
 
-This document specifies a set of coding guidelines including code style,
-formatting and file structuring and organization that shall be applied when
-contributing code to the Bao project. We strive so that most of the guidelines
-can be automatically checked or even enforced by the CI pipeline and try to
-minimize guidelines which can not be automatically addressed. However, in the
-few instances this is not possible, responsibility falls upon code reviewers
-and maintainers to uphold these guidelines are applied as much as possible.
+This document specifies a set of coding guidelines, including code style,

+contributing code to the Bao project. We strive to ensure that most of the
+guidelines can be automatically checked or even enforced by the CI pipeline and

+is not feasible to automatically enforce certain guidelines, the responsibility
+lies with the code reviewers and maintainers to ensure that these guidelines

+C Language
+----------
+
+The coding style and guidelines for C development are heavily influenced and
+constrained by the MISRA C:2012 guidelines, which should take precedence above
+all others in this document or elsewhere.
