# Introduction

Download the latest release of OpenGeoSys from the Releases-page. Be sure to pick the correct file for your operating system.

## Installation

OGS itself is a simple executable file so you can put it anywhere you like. For convenience you may put into a location which is in your PATH-environment variable which allows you to start the executable without specifying its full file path.

Download the latest benchmark files from GitHub as a .zip-package. Unzip it. See the Benchmarks section for more information.

## Running

OGS is a command line application and requires the path to a .prj-file as an argument.

To run it open a new command line shell (called cmd.exe). Now simply type ogs (if the executable is in your PATH-environment variable) or specify its full path (e.g.: C:\Users\MyUserName\Downloads\ogs.exe) and hit ENTER.

OGS prints out its usage instructions:

PARSE ERROR:
Required argument missing: project-file

Brief USAGE:
ogs  [--] [--version] [-h] <PROJECT FILE>

For complete USAGE and HELP type:
ogs --help

You can see that there is the project-file missing.

Then simply supply the path to a project file as an argument to the OGS executable:

$ogs .\Path\to\BenchmarkName.prj To run it open a new command line shell (Terminal). Now simply type ogs (if the executable is in your PATH-environment variable) or specify its full path (e.g.: ./path/to/ogs) and hit ENTER. OGS prints out its usage instructions: PARSE ERROR: Required argument missing: project-file Brief USAGE: ogs [--] [--version] [-h] <PROJECT FILE> For complete USAGE and HELP type: ogs --help You can see that there is the project-file missing. Then simply supply the path to a project file as an argument to the OGS executable: $ ogs ./path/to/BenchmarkName.prj
