The goal of this guide is to establish base installation, initial configuration, and connectivity testing to a point that docuflow d4i components can communicate with one another and allows configuration of the software. 

The docuflow application consists of a core Transformation engine and a series of connectors. Each connector has one or more connections defined which provide the information required to connect to the end applications.

NOTE: docuflow d4i was previously known as TRex and there are still occasional refereces to this name in the product
