As working with GN4 browser and I4 is very similar as working with Ted4/Fred4 (besides functional differences, explained in Functional differences between GN4 browser and client interface), such procedures are described throughout this documentation, within topics that also describe procedures of working with Ted4/Fred4.
For example, to get to know the browser work area, look at the paragraphs in the GN4 Work Area, marked as "GN4 browser". See also Run GN4, Log on and off, Organizing Work, Working with Content and other topics in the Table of Contents.
