STFax 4 should ship with:
STFax 4 requires Magic User Interface (MUI) to be installed on your system, so if you do not have MUI installed, please install this before you continue.
You can obtain MUI from the Aminet, local PD library or a magazine cover-cd.
STFax 4 needs to have MUI already installed on your system to operate. If you have a new version of MUI (v3.8+) then you can proceed with the STFax 4 installation, if not then you should go back to the section about installing MUI on your system.
Insert the STFax 4 CD-Rom into your CD drive and double-click on "Install". The standard Amiga installer window will appear and you will be asked which installation mode you require (we recommend "intermediate") and then click to proceed.
The installation process will ask you where you want to install STFax 4, will ask for your serial code, will then create the necessary drawers and copy the accompanying files.
