+# 👮 Pull Request Checklist
+
+## 📝 Description
+
+- This PR contains the code to create a PR checklist that will help the team in identifying a few common points that needs to be checked while raising a PR.
+
+## 🎫 Associated JIRA tickets
+
+- [SCD-18](https://antstack-datamesh.atlassian.net/browse/SCD-18)
+  - A screenshot followed by the description of the ticket. This ticket deals with creating a common PR checklist template which will be improved continuously to help the developer.
+  - Any additional information for testing the ticket.
+
+## ⚔️ Mandatory Checks
+
+- [ ] Is the functionality working as expected?
+- [ ] Are the comments are clear and useful, and mostly explain why instead of what?
+- [ ] Does it match the required coding standards?
+- [ ] Is the performance up to the mark?
+
+## 🛠️ Regular Checks
+
+- [ ] Spell Checks.
+
+## 🗡️ Optional Checks
+
+- [ ] Schema Changes
+
+## 🤳 PR Self-Review
+
+- **DRY**: Don't repeat yourself
+- **YAGNI**: You aren't gonna need it. Make sure you're not over-complicating something just to try & make it more future-proof 🙅‍♂️
+  - P.S. According to Fowler, "Yagni only applies to capabilities built into the software to support a presumptive feature, it does not apply to effort to make the software easier to modify."
+- A link to some of the [best practices](https://github.com/andela/bestpractices/wiki/Git-naming-conventions-and-best-practices) for creating a PR
