+# Question Service
+
+## Overview
+
+Question service leverages [BeautifulSoup](https://www.crummy.com/software/BeautifulSoup/) as a HTML Parser/Web Scraper, used on [this webpage](https://bishalsarang.github.io/Leetcode-Questions/out.html). The HTML parsed is then stored as a string in our database, using [html-react-parser](https://github.com/remarkablemark/html-react-parser) to convert the HTML string to DOM elements.
+
+On top of that, it provides an **additional** comment/discussion section, which is meant to act as a discussion space for users to discuss potential solutions or give insights.
