Hi Archana:
Unfortunately, we don't have an easy wy for contributors to make edits to the wiki, and because this project is no longer actively maintained, that's unlilkely to change.
However, if you're willing to do things a bit manually: If you clone the wiki repo and publish it to a separate GitHub repo, make your changes there, and then ping me with a pointer to your branch, I can merge your changes in to the wiki:
You can clone the wiki here:
