Thanks.

Well, yes and no: For a full example, it would also include a sentence
describing what it is about plus the g.region command to set the
computational region etc.

To make the screenshot more attractive (about screenshot size and
quality, see https://trac.osgeo.org/grass/wiki/Submitting/Docs#Images),
we could include the shaded terrain as background:

g.region raster=elevation
r.contour in=elevation out=contours levels=60,90,120,150 --o
d.mon wx0
d.rast elevation_shade
d.vect contours color=red

best,
Markus
