Once it's set up you can leave it to get on with it. You may need to rethread it if the thread breaks, change the bobbin when it runs out, and change the colours when necessary.
But you will be responsible for choosing the fabric, the design, the colours, the placement etc, and for setting it up correctly with the stabiliser in the hoop. You can bet that if Iminei and I were to do the same embroidery design, the end results would be far from identical.
