+Automatic Code Formatting
+-------------------------
+
+> **NOTE:** clang-format is a helpful tool but please don't use it blindly!
+
+s390-tools provides a ClangFormat (https://clang.llvm.org/docs/ClangFormat.html)
+configuration file - see [`.clang-format`](.clang-format). It can be used to
+format your C/C++ code automatically.
+
+Clang-format can format a single file or multiple files at once. For example, to
+format `main.c` in place, run the following command in a terminal:
+
+```bash
+clang-format -i main.c
+```
+
+In order to format only your current staged changes use the clang-format git
+plugin:
+
+```bash
+git clang-format --staged
+```
+
+See also `git clang-format -h`.
+
+Automatic Editor Configuration
+------------------------------
+
+s390-tools provides a EditorConfig (https://editorconfig.org/) configuration
+file - see [`.editorconfig`](.editorconfig). EditorConfig defines coding style
+rules (such as indentation size, use of tabs, etc.) and is supported by most
+common editors natively or via plugins.
