+KiCAD
+=====
+
+KiCAD can have a [KiCad database library](https://docs.kicad.org/master/en/eeschema/eeschema.html#database_libraries).
+Running the `kicad_lib.rb` script will create tables (actually views) for each partdb category to be used by KiCAD.
+The views are added without the `partdb.db` database file itself.
+The script will also create the `partdb.kicad_dbl` library file.
+This is the file to be used by KiCAD to add the database library.
+But first you also need to install and configure ODBC so KiCAD can actually access the database:
+
+~~~
+# install ODBC
+sudo pacman -S unixodbc
+# install OBDC sqlite driver
+pikaur -S sqliteodbc
+# fix ODBC sqlite configuration
+sudo sed -i 's|/usr/lib64/libsqlite3odbc.so|/usr/lib/libsqlite3odbc.so|g' /etc/odbcinst.ini
+sudo sed -i 's|/usrl/lib64/libsqlite3odbc.so|/usr/lib/libsqlite3odbc.so|g' /etc/odbcinst.ini
+sudo sed -i 's|/usr/lib64/libsqliteodbc.so|/usr/lib/libsqlite3odbc.so|g' /etc/odbcinst.ini
+sudo sed -i 's|/usrl/lib64/libsqliteodbc.so|/usr/lib/libsqlite3odbc.so|g' /etc/odbcinst.ini
+# add database
+cat << EOF | sudo tee -a /etc/odbc.ini
+[partdb]
+Description=electronic parts database
+Driver=SQLite
+Database=<path to partdb.db>
+Timeout=2000
+EOF
+# ensure it works
+isql partdb
+SELECT * FROM part LIMIT 1;
+exit
