Can i work on this?

[jananiravi]

made minor changes. Yes, go for it, @awasyn!

I would like to suggest that we deprecate the functions and display update message instead of simply renaming them. I am assuming that these are functions already in use by user. @jananiravi

This is a great suggestion in general, @awasyn! In this particular case, the repo is brand new and the only users are you (outreachy) and us! It's yet to go into widespread use. So for this instance, we plan to force-change the names and move on from there. In the future, once the package is in public use, depracation is the right way to go!
