-# MarketWatchConvert
+# MarketWatch Convert
+
+## Overview
+
+Converts scraped data from the MarketWatch watchlist to the desired format.
+
+## Requirements
+
+```.NET 8.0```
+
+## Installation
+
+Unpack ```MarketWatchConvert.zip```.
+
+## Usage
+
+This application converts scraped data from the MarketWatch watchlist in a CSV format into a fixed defined format. It takes into account the status of the company (open/closed) and subtracts the difference if necessary.
+Run ```MarketWatchConvert.exe``` with the path to the input file as a command line argument (or simply open the input file with this application). The program will create an output file with the same name as the input file and ```.txt``` extension and will also copy the output to the clipboard.
+
