 This Repository features C source code i wrote to learn c. Currently the most advanced program included is an
 unfinished implementation of the huffman algorithm.
 
-Some programs make use of outdated and unsafe functions such as gets() or scanf(), which **should never be used**.
+Some programs make use of outdated and unsafe functions such as `gets()` or `scanf()`, which **should never be used**.
 That is the case, because we were teached to use some of these in programming classes. Ideally, all uses
 of these unsafe functions should include a comment explaining why this is bad and also include and implemented
 alternative, but that may not always be the case.
 
 All code in this Repository was written on and for a Linux x86_64 system. It might not work on other systems.

+### Note:
+
+`scanf()` is not inherently unsafe, but must be handled very careful and isn't recommended by most, so i have
+chosen to classify it as unsafe. If you know exactly what you are doing using `scanf()` seems to be acceptable.
+I consider the use of `scanf()` to be bad practice.
