+# Contributing Guide
+
+## 🚀 Getting Started
+
+* Fork the [parseArgs repo](https://github.com/pkgjs/parseargs) using the Fork button on the rop right
+
+* Clone your fork using SSH, GitHub CLI, or HTTPS
+
+  ```bash
+  git clone git@github.com:<GITHUB_ID>/parseargs.git # SSH
+  gh repo clone <GITHUB_ID>/parseargs # GitHub CLI
+  git clone https://github.com/<GITHUB_ID>/parseargs.git # HTTPS
+  ```
+
+* Change into your local parseargs project directory created from the step above
+
+  ```bash
+  cd parseargs
+  ```
+
+* Add pkgjs/parseargs as your upstream remote branch
+
+  ```bash
+  git remote add upstream git@github.com:pkgjs/parseargs.git
+  ```
+
+* Create a new branch for your awesome work
+
+  ```bash
+  git checkout -b <BRANCH_NAME>
+  ```
+
+* Confirm tests are passing
+
+  ```bash
+  npm test
+  ```
+
+* Commit your work. See the [`Pull Request and Commit Guidelines`](#-pull-request-and-commit-guidelines) section
+
+* Push to your branch
+
+  ```bash
+  git push -u origin <YOUR_BRANCH>
+  ```
+
+* Open a pull request
+

+
+## 📝 Pull Request and Commit Guidelines
+
+* Multiple Commits would ideally be [squashed](https://docs.github.com/en/desktop/contributing-and-collaborating-using-github-desktop/managing-commits/squashing-commits) and merged into one commit wherever possible
+
+* Do not use the merge button
+
+* Commit messages would ideally reference the associated changed subsystem or behavior.
+
+* Pull Requests for a new feature or bug fix must include tests. Additional tests or changes to the existing ones can made in the following file: [test/index.js](test/index.js)
