Use Markdown files to store content

[rohitkg98]

Currently, we render content straight from a list of JS object. This will get cumbersome.
Moving forward, we could create a separate folder for content which contains .md files. We can parse and render these files.

Let me know what you think of it

Currently I have stored the JS object in a different file so that it doesn't get mixed up with the logic. I've never worked with .md for parsing and rendering, but I'll look into it.
