@arjunrkaushik A few quick tips for making a good PR -

1. The branch name should be descriptive and different words should be separated by hyphens (No other characters should be used except lowercase English alphabet and '-').
2. The commit messages should never include keywords like Fixes #bugNum because it leads to unnecessary mentions of the commit in the issue description.
3. When PR is ready for review, add a "PTAL" comment by mentioning any reviewers like - @{reviewerName} PTAL. This comment ensures that PR is ready to review from your side (if the author does not leave a PTAL comment then the reviewer may think that the author wants to add more commits in the PR)

I suggest going through the Making a Code Change Instructions once.
