 ## Overview
 The Holistic Optimization Program for Electricity (HOPE) model is a transparent tool for evaluating electric sector transition paths regarding power system planning, system operation, optimal power flow, and market designs. It is highly configurable and modulized programming coded in the  [Julia](http://julialang.org/) language and optimization package [JuMP](http://jump.dev/). The HOPE consists of multiple modes for modeling modern power systems and electricity market, including:
-1. GTEP mode: a generation & transmission expansion planning model
-2. PCM mode: a production cost model
-3. OPF mode (under development): an optimal power flow model
-4. DART mode (under development): a bilevel market model for simulating day-head and real-time market
+1. `GTEP` mode: a generation & transmission expansion planning model
+2. `PCM` mode: a production cost model
+3. `OPF` mode: (under development): an optimal power flow model
+4. `DART` mode: (under development): a bilevel market model for simulating day-head and real-time market
+
 Users can select the proper mode of HOPE based on their research needs. 
 
 The HOPE model was originally developed by a team of researchers in Prof. [Benjamin F. Hobbs group](https://hobbsgroup.johnshopkins.edu/) at [Johns Hopkins University](https://www.jhu.edu/) The main contributors include Dr. [Shen Wang](https://ceepr.mit.edu/people/wang/) and Dr. [Mahdi Mehrtash](https://github.com/MahdiMehrtash).
