The easiest way to learn how to use this machine is to gather your supplies: embroidery thread (choose a few basic colors), machine embroidery bobbin thread (important to use this and not the top thread), medium weight cut away stabilizer and scraps of fabric.
Open the manual right next to the embroidery machine.
Read and follow each step.
Hoop the fabric and stabilizer and then stitch out a few of the built-in designs. The select a frame and stitch that around the design. Bump up the position of what you have stitched out and select a few letters to put under it.
It may not be perfect the first time, but if you keep playing you will soon be very proficient.

Relax and enjoy a great craft.
