 ### Compilation Notes
 * 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)
-* Audio call support is automatically enabled if all dependencies are found
-* If you want to build toxic without audio call support, you can use `make DISABLE_AV=1`
-* Sound notifications support is automatically enabled if all dependencies are found
-* If you want to build toxic without sound notifications support, you can use `make DISABLE_NOTIFY=1`
+* Additional features are automatically enabled if all dependencies are found, but you can disable them by using special variables:
+  * `DISABLE_AV=1` → build toxic without audio call support
+  * `DISABLE_SOUND_NOTIFY=1` → build toxic without sound notifications support
+  * `DISABLE_DESKTOP_NOTIFY=1` → build toxic without desktop notifications support
 
 ### Packaging
 * For packaging purpose, you can use `DESTDIR=""` to specify a directory where to store installed files
