+# Distance Calculating App
+Calculating distance between two locations is a basic requirement if you are working with raw location data. This app calculates distance between two geo-locations. You can get distance in kilometers between two locations just by entering names of the locations.
+
+## Quick Start:
+
+- Change Directory
+
+``` cd .\Rotten-Scripts\Python\Distance_Calculator_App\ ```
+
+- Install requirememnts
+
+`pip install -r requirements.txt`
+
+- Run python file
+
+`python main.py --firstlocation <enter first location here> --secondlocation <enter second location here>`
