+# Contributing to param-validator
+
+Hey! We are glad you want to help us improve express-validator.
+
+Even though we will appreciate any contribution, please make sure to read [this guide](https://guides.github.com/activities/contributing-to-open-source/) on how to contribute on GitHub.  
+It's a short read and will get you started on how most things work.
+
+## Issues
+
+In case you are having issues while using express-validator, make sure to browse through the project's issues before opening a new one.  
+Someone else may have had the same problem before.
+
+When opening a new issue, please provide us some code that reproduces the errors you're getting, perhaps some logs too, express-validator version, etc.  
+Every detail you can give will be of great help.
+
+## Pull Requests
+
+Do you want to dedicate your time to help improve the codebase? Great! Then submitting a pull request is the best way to do this.
+
+If you are a new contributor and you want to improve the codebase you can follow these five steps:
+
+1. Fork the repository.
+2. Choose an issue to work on.
+3. Work on the issue locally.
+4. Push to your fork.
+5. Open a Pull Request.
+
+In case you opened a issue, then fixing it yourself is the fastest way to get it done.  
+Otherwise, feel free to browse through the open issues and find some ideas on what needs some implementation.
+
+We have some requirements regarding pull requests:
+
+- Every pull request should include tests.
+- **The builds must pass**; if they don't, click through, find out why, and fix it.
+- If you're adding/changing functionality, make sure to reflect the changes in the readme file.
+
+---
+
+Finally, remember: **this is an open source project. We contribute whenever our time allows us.**
