Hey @KaushikML,
Unfortunately, this PR doesn’t include any meaningful changes, typos and breaking links are supposed or just content changes are to be reported not fixed. You can do so on the specific two repositories that we provided. In the future, please ensure that a PR in this repo is raised only if you’ve made substantial updates or solved a particular issue. This helps keep the process efficient and organized.
This being a part of an assignment in api fellowship would be counted since you were supposed to create a pr but wont be merged since this is not that relevant of a change. I’m sure you understand, and I appreciate your cooperation on this. We will be closing this PR for now.
