 ## Notes

 #### Compilation variables
-* You can add specific flags to the Makefile with `USER_CFLAGS=""` and/or `USER_LDFLAGS=""`
-* You can pass your own flags to the Makefile with `CFLAGS=""` and/or `LDFLAGS=""` (this will supersede the default ones)
+* You can add specific flags to the Makefile with `USER_CFLAGS=""` and `USER_LDFLAGS=""` passed as the arguments to make or as environment variables
+* You can use CFLAGS and LDFLAGS environment variables to add specific flags to the Makefile
 * Additional features are automatically enabled if all dependencies are found, but you can disable them by using special variables:
  * `DISABLE_X11=1` → build toxic without X11 support (needed for focus tracking)
  * `DISABLE_AV=1` → build toxic without audio call support
