Hi @amcclain
I am looking for good-first-issues and I think this will be the perfect issue to start.
Can you please assign this issue to me?

Hi @RahullRawat - thank you for your interest and offer, but we are not currently set up to accept changes from external contributors. While we practice "coding in the open" with our libraries here and make their source available, we manage changes to them pretty tightly and handle those within our XH team, as we use these libraries in our work with clients.

Again, appreciate your offer and wish you the very best.

Ohh okay, no problem @amcclain
