Here's how you can do that: 

On web

On app

Dashboard --> Goal in which you'd like to set up the SIP --> Invest --> Start SIP --> Fill up the amount, duration, risk level, etc. --> Review and Confirm SIP.

Please note that you would be able to set up a SIP from your dashboard up to 1 day prior to the scheduled SIP start date. For example, if the scheduled SIP start date is January 7, you can set up the SIP till midnight on January 6.

If you wish to invest in the funds of your own choice (and not exactly as per our recommendations), you can refer to this FAQ.
