+PyDesigner in Container
+=======================
+PyDesigner can run on all major platforms (x86, x64, and ARM) via Docker container technology. The containerized
+form of PyDesigner is called `NeuroDock`_ and comes preloaded with PyDesigner, FSL, and MRtrix3.
+
+Obtaining the `FSL`_ software typically requires `registration`_. Therefore, we requeust users of NeuroDock who have
+not previously registered as a user of the FSL software complete the registration process. This allows developers
+of FSL to be recognized for the utilization of their software.
