+Add/link *printf.c* to your project and include *printf.h*. That's it.
+Implement your low level output function needed for `printf()`:
+```C
+void _putchar(char character)
+{
+ // send char to console etc.
+}
+```
+
+Usage is 1:1 like the according stdio.h library version:
+```C
`int printf(const char* format, ...);`
`int sprintf(char* buffer, const char* format, ...);`
`int snprintf(char* buffer, size_t count, const char* format, ...);`
+```
**Due to genaral security reasons it is highly recommended to use `snprintf` (with the max buffer size as `count` parameter) only.**
`sprintf` has no buffer limitation, so when necessary - use it with care!
