Hunter's comment
With Mergify, no need to merge pull request manaually. Mergify will automatically merge the pull request once it is ready for merging. As a developer, you will have a lot of things to do, will you love to go through stressful processes of assessing a pull request on your project?
With Mergify all these are solved.
Configure the service, activate Mergify on your repository, set your rules, sit back and watch Mergify do the rest for you.
