For irreversible upgrade, perform the following steps. If you want to switch back to Kicad 4 at a later point, make a backup of these folders instead of removing them.

• then, install from package as described

#### Global library paths

While collaborating on a large project with other people, it is possible that different versions of KiCad are being used in your team, and with that also different versions of the component libraries. Therefore, we would recommend using the library repositories directly pulled and regularly updated from KiCad's github page. The repositories are called kicad-symbols, kicad-footprints and kicad-packages3D respectively.

Store them, for example, in your home directory in a folder named ~/kicad. Then, open KiCad and from the menu Preferences open “Environment Variable Configuration”, where you now simply have let the KICAD_SYMBOL_DIR point to ~/kicad/kicad-symbols (or where you have cloned the kicad-symbols repository to), KISYS3DMOD to ~/kicad/kicad-packages3D and KISYSMOD to ~/kicad/kicad-footprints.

It is possible that the ~/ path description will not be correctly handled by KiCad, which is why you may need to write the expicit path, e.g. /Users/yourname/kicad

#### Project-specific libraries

Any symbol or footprint library that is part of a specific project should be included directly in the schematics or PCB editor under Project Specific Libraries and using relative paths (with the \${KIPRJMOD} macro).
