Help learning powershell scripting

Here is the whole situation, I just started a job as a systems administrator and am looking to streamline the imaging process a bit. The department who builds our images, people in my department install, are seriously lacking drivers for most devices. I have all the drivers but am having a time learning how to build the powershell scripts to call the device installers, or call the unknown device from device manager and have it install from a local file. Any help would be appreciated.
