Increase SSD size for OS

I have a Dell Inspiron 3780 x64 using Win 10. My OS is on a 128 GB SSD and the storage is a 1TB HD. (standard) with 16 GB of memory. I want to clone my OS that's on the 128 SSD to a 256 GB SSD (the max for this system) because I need more space for apps and the files they produce. WHAT EQUIPMENT WOULD I NEED TO DO THIS??? I do not know what these items look like so any photos or video links would be very much appreciated. Thank you in advance.
