+# How to configure clang‐format
+
+## Overview
+clang-format is an utility to format source code in several languages 
+according to predefined settings. Settings for auto-formatting of C source 
+files are summarized below, and should be saved in .clang-format file in root 
+folder. These settings are chosen to closely match the formatting style used.
+
+## Configuring Editors
+### Visual Studio Code
+Install the C/C++ extension and customize settings.json to include:
+
+    "C_Cpp.clang_format_path": "/path/to/<clang-format-executable>",
+    "C_Cpp.clang_format_style": "file",
+    "C_Cpp.clang_format_fallbackStyle": "none"
+
+### Emacs
+Add the line
+
+    (load "/path/to/clang-format.el")
+
+to `~/.emacs.d/init.el`. Format a source file with `M-x clang-format-region`.
+
+### CLion
+* Add the .clang-format file to the Kratos root directory as 
+  explained aboveGo to File->Settings->Tools->External Tools 
+  and click on the plus sign. A window should pop up. 
+  Choose a name, for example "clang-format"
+* For the Tool settings tab I'm using this configuration:
+  - Program: clang-format (you should use the name of your executable here)
+  - Parameters: --style=file -i $FileName$
+  - Working directory: $FileDir$
+Now, with your file open, you can go to Tools->External tools and run the config above. It basically calls clang-format and does inplace formatting using the style define in the first .clang-format file found in a parent directory.
