[palash25]

https://github.com/rust-lang-nursery has lots of popular rust crates and lots of issues for which mentors are available.

Thank you for raising this issue @palash25.

I see plenty of good first issues is projects like rust-clippy
https://github.com/rust-lang-nursery/rust-clippy/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22

Definitely worth adding.

i would like to take this one if possible :)

just to be clear, you want to add a new card of rust lang nursery to the github page right,
with the link @Roshanjossey provided? or it better be the main issues page? or the repo page?

[Roshanjossey]

@omer2500, great. Go with the link in my comment. I believe it's better to take users to good first issues.
