+### Process ###
+
+* Reviewers are listed in the CODEOWNERS file
+* Code format guidelines
+
+RDC uses the clang-format tool for formatting code in source files.
+The formatting style is captured in .clang-format which is located at
+the root of RDC. These are different options to follow:
+
+   1. Using pre-commit and docker - `pre-commit run`
+   1. Using only clang-format - `clang-format -i \<path-to-the-source-file\>`
