Sorry for the late reply. You've probably already figured it out in the meantime? There's not really that much to it.
You can start by loading an already installed Windows font and modifying that, then giving your font a new name in the Font Properties dialog and saving the font with a new filename (don't save straight into Windows' Fonts folder, though).
Now from the File menu choose Install font to make the font available to Windows (or drag the font file to the Windows Fonts folder). The font you made should now be available to Windows programs like any other bitmap font.
Ask if there's anything specific you'd like to know - there's still no manual for this thing.
