The DiFX Documentation Pages
Getting Started with DiFX
If you have not already, please join the DiFX-Users mailing list - to do this, go to https://listmgr.nrao.edu/mailman/listinfo/difx-users and sign up.
You might find it enlightening to browse the SVN source tree.
Read the Reference Manual which has a lot of detail about the NRAO installation of DiFX and a lot of information about the helper programs for configuring the correlator and managing the output.
The (now-defunct) forum on the old DiFX-users Google Groups page (https://groups.google.com/forum/#!forum/difx-users) might also have useful information, so feel free to swing past there and search old threads for answers to questions you might have.
