Need advice on allocation of salary

Hi all.

I am 24F,working since sept 25. My current in-hand is around 96k. Need advice on building a portfolio from scratch.

I am basically not investing anything at all. Reason being my family income is around 25k. My parents do not have any savings for any future events like health issues, education of my younger sister, marriage etc. Even though they do not take any money from me, I know I am responsible for all these future events.

Concludingly, I am keeping all my salary in my account. I have made 1 FD for 1lac as of now. Ik I need to put money in mutual funds- nifty 50 maybe. My only caveat is that if I am suddenly in any emergency, I wont have enough funds.

Hope my explanation helps.

P.s. My monthly expense is under 25k
