+  summary: The open source spice simulator for electric and electronic circuits
+  description: |
+    ngspice is the open source spice simulator for electric and electronic circuits.
+
+    Such a circuit may comprise of JFETs, bipolar and MOS transistors, passive elements
+    like R, L, or C, diodes, transmission lines and other devices, all interconnected
+    in a netlist. Digital circuits are simulated as well, event driven and fast, from
+    single gates to complex circuits. And you may enter the combination of both analog
+    and digital as a mixed-signal circuit.
+
+    ngspice offers a wealth of device models for active, passive, analog, and digital
+    elements. Model parameters are provided by the semiconductor manufacturers.
+    The user add her circuits as a netlist, and the output is one or more graphs of
+    currents, voltages and other electrical quantities or is saved in a data file.
+
+    Note:
+      This build was configured with `--enable-xspice --enable-cider --enable=openmp`
+      See the [build script](https://git.io/JfVZX) for more specifics.
