After installation, visit the CoWIN self-registration portal.
You'll see a button to start the bot. Click on that button, fill in your details, and click on book my vaccine.
The bot will automatically fill in all your details on the CoWin website, and you only need to enter the OTP.
Once you enter the OTP, the bot will continuously search for available slots, and if found, it will auto-book it for you.

## Advanced Features

Multi-User Accounts
The bot supports accounts with multiple registered members. You need to select the correct Member Number On Dashboard.

Vaccine Preference
You can select the vaccine type from Covishield / Covaxin / Sputnik. You can also limit your search for only free vaccines.

If selected, the bot automatically pauses after it reaches the 20 search rate limit in 15 mins and it automatically continues after the cool-down period.

Audio Alerts
You get an audio alert when a slot is found or when you need to enter your OTP so that you never miss the opportunity to book a slot.
