+# Formatting
+
+The Nilstrieb C Style Guide Edition 2 mostly follows the principle of maximal readability.
+Code, especially C code, is mostly read (by security researchers to find the vulnerabilities),
+and therefore readability comes before writability.
+
+## Control flow
+
+Never use braces with `if`/`while`/`do`/`for` statements as they introduce clutter. If your
+body cannot fit into a single line, make a new function instead.
+
+```c
+   #include<stdio.h>
+
+   void foo_if_body() {
+      printf("Hello, ");
+      printf("World!");
+   }
+   
+   void foo() {
+      if (true)
+          foo_if_body();
+      else
+          printf("True was false!");
+   }
+```
+
+## Identation
+
+C code must be indented with 3 spaces. The toplevel should be indented as well.
+
+```c
+   #include<stdio.h>
+
+   int main() {}
+```
