Hey Manish, welcome. If you're new to NetLogo, I recommend reading through some of documentation first. A good starting point is the sample model walkthrough, then checking out the interface guide, then the tutorials, and finally reading the programming guide.
Once you're familiar with NetLogo a bit, you can look at the wiki documentation for contributors for desktop NetLogo or for NetLogo Web, depending on which project you're interesting in.

I assume since you posted here in the Google Summer of Code channel that you're interested in participating in that program. Just to let you know, the CCL did not participate this past year (2020) in GSoC and I cannot guarantee that we will participate in 2021, either.
