One of the things I like about Kicad is it supports libraries right off of Github so you can have the latest PCB footprints as they’re added there. But there are currently 85 libraries on the main Kicad github page, so it’s difficult to get started and find the stuff you want.
To make it easier to get started, I entered the name and Github URI for each library into my fp-lib-table file and uploaded it to a gist: https://gist.github.com/xesscorp/c09155aaa954b06b344a . All anyone has to do is load the contents of this gist into their own fp-lib-table file and they’ll have immediate access to all the public Kicad PCB footprint libraries.
Once you have those, you can use the library browser in pcbnew to look at the footprints in various libraries and decide which ones are useful to you. Then you can comment-out the ones you don’t need/want.
These libraries would have helped in a few of the forum topics we’ve already had: 1) there is a library of fiducials already built that can be used as-is or modified and 2) another library with single-pin pads/holes that could be used for building 0.1" prototyping areas.
If anyone knows other Github-based libraries, I can add them to the gist. The only requirement is they have to be in the Kicad .pretty format (whatever that is).
