This document is intended for potential or actual Gekko users who wish to get a quick look at Gekko's capabilities, without having to read lots of help pages etc. The guide is centered around a concrete practical simulation example (for which data can be downloaded). The reader has two options: (a) download Gekko and the data set, and run the examples step by step along with the guide, or (b) just read the guide without installing/using Gekko, to get a quick idea of the software.

Readers of type (b) -- i.e. readers just wanting a quick overview without any fuss -- may jump directly to section 3 below. The guide is designed for Gekko 2.0, in sim-mode (cf. the MODE command). A data-mode guide is planned.

• Section 1: Installation and download of example data
• Section 2: Graphical interface, and some basic concepts
• Section 3: Performing a historical simulation
• Section 4: Performing forecast scenarios (multiplier analysis)
  
• Section 5: Add-factors etc.
  
• Section 6: Goal-search, exogenization
• Section 7: Forward-looking models [to be done]
