This is how it works:
1) Go to
https://indianvisaonline.gov.in/ and apply for "evisa". You will need to upload passport copy pdf and digital photo jpg format.
2) After you finish application, and pay $40 fee (for 1 year visa), you will get acknowledgement of application in your email.
3) You will get another email within 72hrs with decision. They say 72hrs, but it is a lot faster under normal circumstances.
4) if you are "GRANTED" visa, go back to the website above and click on apply evisa> check visa application status. There you will be able to print your official e-visa with your pic, QR code and conditions of the visa eg. tourist, conference, medical etc. to carry with you to the airport.
