A detailed documentation to setup noti with the push notification providers on windows

[Hx2-code]

Its really difficult to setup noti with push notifications on windows without a proper detailed documentation unlike on linux.

Happy to merge any documentation updates! I don't have access to any Windows machines. :/

Thanks for your reply. I figured out by myself about how to setup push notification on windows.

For anyone having the same issue, the basic steps for installations on windows are:

1. Download the latest release
2. Create a new folder: C:\Program Files\Noti
3. Extract the exe file into the new folder (e.g. by using 7zip)
4. Add C:\Program Files\Noti to the Path variable (here is a guide: https://www.architectryan.com/2018/03/17/add-to-the-path-on-windows-10/)

I might submit a pull request with a more thorough explanation later, but I'm glad if someone else does it!

Note: On Windows, it's better to use program_name; noti instead of noti program_name as powershell commands don't get executed correctly (e.g. noti echo hello fails, but echo hello; noti works just fine.
