I'm not sure exactly what we want here @zairahira, but I think we should try to come up with something a little longer. It would be nice to have a paragraph or two for each project.

Perhaps this would be good enough for now, as it is an improvement.

I have used the same description as the existing projects to get rid of the default line.
We can definitely work on adding an extended description.

What about if we use the intros from the intro.json @moT01 ? For example:

"intro": [
          "Python is a powerful and popular programming language widely used for data science, data visualization, web development, game development, machine learning and more.",
          "In this project, you'll learn fundamental programming concepts in Python, such as variables, functions, loops, and conditional statements. You'll use these to code your first programs."
        ]

@naomi-lgbt was working on some of these in the other projects, here's where she's at: https://github.com/freeCodeCamp/freeCodeCamp/pull/55004/files

So maybe you can use those as examples for what we generally want - or maybe you can pair with her see what her process is or something.

@moT01 and @naomi-lgbt, I have attempted to update the index.md for the shortest path algorithm. Please share your views on it.

Yes! This is an excellent starting point!
