Does a prompt guide exist? Does parameters exist?

We do not have a prompt guide. Right now you can use the following parameter:

• [outline-strength=80] 1-100 adjusts the creativity on text effects. Higher number will give you a tighter fit to the outline. Lower numbers will give you the more swirly effects.
• [avoid=green, cars] - list of concepts we’re going to try to steer the generation away from

These parameters are subject to change.
