+# Contributing Guidelines
+
+## Asking Questions
+Before submitting a question, please check the [Troubleshooting Guide](https://docs.lubelogger.com/Installation/Troubleshooting) and search through existing issues.
+
+Ideally, the Issues tab should only consist of bug reports and feature requests instead of debugging your LubeLogger installation.
+
+## Feature Requests
+Feature Requests are cool, but we do want to avoid bloat and scope/feature creep.
+
+Read [this](https://github.com/hargata/lubelog/wiki/Scope-and-Purpose) to better understand the scope and purpose of this project.
+
+LubeLogger is a Vehicle Maintenance and Fuel Mileage Tracker. 
+It is not and should not be used for the following:
+- Project Management Software(e.g.: Jira)
+- Budget Management(e.g: YNAB/Actual)
+- Inventory Management
+
+Before submitting a feature request, please consider the following:
+- Will this feature benefit more than just a niche subset of users
+- Will this feature result in scope creep
+- Has this feature already been requested/exist
+
+## Bug Reports
+Please fill out the issue template for bug reports.
+
+## Security Vulnerabilities
+Contact us via [Email](mailto:hargatasoftworks@gmail.com)
+
+## Submitting Pull Requests
+Pull Requests are welcome, but please consider the following:
+
+CI/CD, Bugs, Tech-Debt Related PRs:
+- Make sure changes are not breaking.
+- If any dependencies are added, they must be cross-platform compatible.
+- Please test changes thoroughly.
+
+Feature Related PRs:
+- Have you requested this feature in the Issues tab
+- Will this feature benefit more than just a niche subset of users
+- Will this feature result in scope creep
+- Do these changes fix a root cause or is it simply a workaround
+
+Ideally, you should first submit a feature request in the Issues tab before submitting a PR just in case it's something we are already working on.
+
+Note the following:
+
+We(the maintainers) are not responsible for cleaning up, testing, or fixing your changes.
+
+If your changes doesn't have a wide-ranging use-case, has not been thoroughly tested, or cannot be easily maintained, we won't merge your PR.
