I just started using KiCad and I'm browsing a bunch of tutorials on how to do things. I found out that digikey has a great feature where you can download a part you want to buy in a multitude of PCB design formats, including KiCad... There are two limitations, the first one not being a very big deal. You're limited to 15 free component downloads per month unless you pay a premium. I don't think I will need much more than that.
But the other thing is that each part comes with it's own files. Each has a .lib and a .kicad_mod. If i want to build a moderately complex circuit_board I'm going to have a dozen different pieces. Am I supposed to merge the libraries together (can that even be done?) Also, the mod file is has the name of the component (NE556D.kicad_mod), but the lib is just called symbols.lib. And now, every time I open the eeshema that holds my project, it tells me "The following libraries were not found: .../Kicad/symbols
So, I can't actually load the file I downloaded from DigiKey. Is there something specific I need to do before I can use downloaded libraries in my projects?
