 This workflow algorithm creates MDWorkspaces in the Q3D, HKL frame using `ConvertToMD <http://www.mantidproject.org/ConvertToMD>`__. 
 
+Setting the UB matrix
+######################################
+
 *u* and *v* are required. *u* and *v* are both 3-element vectors. These specify how the crystal's axes were oriented relative to the spectrometer in the setup for which you define psi to be zero. *u* specifies the lattice vector that is parallel to the incident neutron beam, whilst *v* is a vector perpendicular to this in the horizontal plane. In UB matrix notation, *u* and *v* provide the U matrix. See `SetUB <http://www.mantidproject.org/SetUB>`__. *Alatt* and *Angdeg* are the lattice parameters in Angstroms and lattice angles in degrees respectively. Both are 3-element vectors. These form the B-matrix.
 
+Goniometer Settings
+#####################
+
 If goniometer settings have been provided then these will be applied to the input workspace(s). For multiple input workspaces, you will need to provide goniometer settings (*Psi*, *Gl*, *Gs*) as vectors where each element of the vector corresponds to the workspace in the order listed in *InputWorkspaces*. You do not need to provide the goniometer settings at all. If you run `SetGoniometer <http://www.mantidproject.org/SetGoniometer>`__ individually on the input workspace prior to running CreateMD, then those settings will not be overwritten by CreateMD.
 
+Merging Individually Converted Runs
+#####################################
+
 If a sequence of input workspaces are provided then these are individually processed as above, and are merged together via `MergeMD <http://www.mantidproject.org/MergeMD>`__. Intermediate workspaces are not kept.
 
+Additional Information
+#######################
+CreateMD uses `ConvertToMDMinMaxLocal <http://www.mantidproject.org/ConvertToMDMinMaxLocal>`__ to determine the min and max extents prior to running `ConvertToMD <http://www.mantidproject.org/ConvertToMD>`__ on each run.
