+# Makefile for efabless design kits for SkyWater Sky130:
+#
+# sky130A = 5-metal backend stack with dual MiM
+#
+# Written by Tim Edwards March 2019
+# efabless corporation
+# updated October 2019
+# updated December 2019 (divide installation sections for individual tools)
+# updated March 2020 (refactored the install process)
+# updated May 2020 (changed to new process name Sky130)
+#
+# Instructions:
+#
+# Modify values below as needed:
+#
+# VENDOR_PATH: points to vendor sources
+# EF_STYLE: 1 for efabless style, 0 otherwise
+# LINK_TARGETS: link back to source or link to 1st PDK when possible
+# DIST_PATH: install location for distributed install
+# LOCAL_PATH: install location for local install or runtime location
+# for distributed install
+#
+# Run "make" to stage the PDK for tool setup and vendor libraries
+
+# If installing into the final destination (local install):
+#
+# Run "make install-local" to install all staged files
+# ("make install" is equivalent to "make install-local")
+#
+# If installing into a repository to be distributed to the final destination:
+#
+# Run "make install-dist" to install all staged files
+#
+# Run "make clean" to remove all staging files.
+#
+# Run "make veryclean" to remove all staging and install log files.
+#
+# For the sake of simplicity, the "standard" local install can be done
+# with the usual
+#
+# make
+# make install
+# make clean
+#
