PR Description 📜

Please include summary related to the issue you have fixed and describe your PR in brief over here by specifying the issue number on which you were working below Fixes # 3862

For my contribution, I made several grammatical and typo corrections to the project’s README.md file. The README.md file is the first look at any project and therefore sets the tone for the whole project. I believe a README.md file that is free from grammatical errors and typos would create a more polished look to the project and would also assist users/contributors that are not very familiar with the English language with an easier time understanding.
