Within KLayout, create the technolgy SKY130 by the menu : [Tools]-[Manage Technologies]
Then press + at the bottom left, you will add a new technology that you can call : SKY130

Then, you can copy the file SKY130.lyp, SKY130.lyt and the 2 directories drc and lvs of that repository in your directory :
$HOME/.klayout/tech/SKY130 (under Linux)
#HOMEDATA#/klayout/tech/SKY130 (under Windows)

Due to few SKY130 GDS cases found and tested, the DRC/LVS files have not been extensively tested and still probably have bugs for some cases.
It was tested on the GDS and spice netlists of the LIB_CASES directory.
The more we can publish SKY130 GDS files, the better those DRC/LVS files.
At that stage, the GDS needs another checks before tape-out.
