 Initiates the probing procedure for Bed Mesh Calibration.  If `METHOD=manual`
 is selected then manual probing will occur.  When switching between automatic
 and manual probing the generated mesh points will automatically be adjusted.
 
+It is possible to specify mesh parameters to modify the probed area.  The
+following parameters are available:
+- Rectangular beds (cartesian):
+  - `MESH_MIN`
+  - `MESH_MAX`
+  - `PROBE_COUNT`
+- Round beds (delta):
+  - `MESH_RADIUS`
+  - `MESH_ORIGIN`
+  - `ROUND_PROBE_COUNT`
+- All beds:
+  - `RELATIVE_REFERNCE_INDEX`
+  - `ALGORITHM`
+See the configuration documentation above for details on how each parameter
+applies to the mesh.
