 The VTUI library is designed to be loaded by standard CBM kernal functions [SETLFS](https://cx16.dk/c64-kernal-routines/setlfs.html), [SETNAM](https://cx16.dk/c64-kernal-routines/setnam.html) and [LOAD](https://cx16.dk/c64-kernal-routines/load.html).
 
-In several assemblers it is possible to load a binary file directly with the sourcecode. for ACME it is done something like this `VTUI !BIN "VTUI0.9.BIN"` and for CA65 it would be done like this `VTUI .INCBIN "VTUI0.9.BIN"`. The ACME and CA65 include files use this method to load the library.

 If an assembler is used to include the binary file, be aware that the first two bytes are a loading address so base address of the actual library will be: `VTUILIB=VTUI+2`.
