 Helps me book the badminton court from HDC automatically.
 Right now  now configuration is added but password's been removed from the repo and I will need to create a file called "Password.txt" to work on the project.
 In the future perhaps it would be much better if I can deploy as a webapp that can be used by friends to schedule an auto purchase of a slot at a perticular time.
+
+## Example Useage
+**`dotnet run -- 22:00`**
+Where `22:00` is the end time of the prefered time. `22:00` is the slot from `21:00 - 22:00`.
+
+Preferably the application will be run close to 8AM around 7:45AM so that there's no need to
