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.

## 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
