Hey @0zAND1z and @rahullenkala,
Welcome to the community! 
I’d recommend starting with:
- https://docs.libp2p.io: it’s work in progress but there’s heaps of useful material for beginners and experts alike.
- https://github.com/libp2p/specs: review the libp2p specs. Also in the middle of an overhaul. Check out the WIP PRs too.
- See this thread: Where to start to use libp2p, for more resources and instructional material on p2p networking in general.
- The rustdocs of rust-libp2p are written with love and care; thanks to @tomaka!
Hope that helps!
