+**NOTE** this step may not be entirely successful for your particular
+system. Building ParaView itself is generally not a significant problem
+but its dependency on particular Qt versions can be a problem.
+
+If you fail at this step due to Qt dependencies, you may have success
+building a slightly older Qt version. Another alternative may be to
+use the ParaView-5.4 sources that were included in the ThirdParty-v1712
+source pack. This, however, has never been tested in combination with
+the OpenFOAM Catalyst insitu visualization.

+
+#### 5.5.x binary package
+
+For general functionality, the paraview version distributed with
+the operating system or a [binary package][download ParaView]])
+may be sufficient for your needs.
+- No known issues with the native OpenFOAM reader.
+
+
+Using a binary package does mean you miss these elements (which may or
+may not be important for you):
+- cannot visualize a `blockMeshDict`
+- cannot build Catalyst insitu visualization
+- no alternative OpenFOAM reader module for some special features not
+  found in the native OpenFOAM reader.

 #### 5.5.x
 - Requires patching for the vtk-m configuration (on some systems).
 - Recommended patching for ParaView Catalyst.
