 # Setup
 Start a GRASS session in a new project with a Cartesian (XY) coordinate system.
-Use [g.region](https://grass.osgeo.org/grass-stable/manuals/g.region.html)
+Use {{< meta links.g_region >}}
 to set the extent and resolution of the computational region.
 Since we are working in a Cartesian coordinate system,
 we can simply create a region starting at the origin
