FARGO3D User’s guide is available in three different formats:

 The html online version. This online help is hosted on the website of the git repository and is always in sync with the last public commit. This is the recommended source of information.

Alternatively, you may prefer these formats that correspond to the version 1.3 of the code, released on August, 3, 2018:

 A pdf file
 An epub file (electronic book format, to read on your favorite mobile device)

Here is an introductory html page (from an ipython notebook) that provides a guided tour to FARGO3D, and here is some more advanced material.
