-Implementierungen in folgenden Dateien
+Makefile
 ======================================
-main.cc
-devices/CGA.h
-devices/CGA.cc
-devices/PCSPK.cc
+I added the -std=c++17 flag to enable better constexpr support.
 
+Clang Tidy
+======================================
+The compile_commands.json is used by clang-tidy.
+To generate it from the makefile, use bear: "bear -- make".
+There are two options that clang doesn't know: -mpreferred-stack-boundary=2 and -mmanual-endbr.
+These should be removed from the compile_commands.json so clang-tidy won't throw errors for every file.
