This is a legacy repository for use with KiCad 4.0.x. It will no longer be maintained. The new repositories are found here:
This repository contains the official schematic and 3D libraries supported by the KiCad library team.
The footprint libraries are the
*.pretty repos themselves and are used online by default. If you want to download them locally, the
library-repos-install.sh scripts in the KiCad source can do this automatically.
