Respected Sir/ Mam ,
I am Zunzarrao Deore, a computer science undergrad. I have just entered my
second year at D.Y. Patil college of engineering, Pune. I am new to open
source contribution but I am well aware of programming languages like C++,
Python, html and CSS also I have moderate  knowledge of Data Structures and
Algorithms.
I would like to contribute to your organizations but could you tell me how
to get started ?
Hoping to hear from you soon.
Regards
Zunzarrao.
