If the dumb layman can understand the copy, then the technical person will understand it too. Write for us dummies that aren’t overly technical, and everyone else will understand.
Note that Copy that sells the product/software is very different than the technical writing needed to explain how to install or structure the module.
Screenshots do a good job speaking to both users. Good reviews can help put the technical users at ease that the module is relatively straightforward installing and won’t cause problems or conflicts.
