+# Contributing to This Project
+
+Thanks for taking a look at my project! This is a personal hobby/side project I work on in my spare time. It’s not designed with collaboration in mind, but I’m happy to accept contributions if you’d like to submit a pull request (PR)—I appreciate anyone willing to build on what I've done already!
+
+## About This Project
+
+As a side project, here’s what you might encounter:
+
+- **Documentation**: It could be minimal, rough, or outdated
+- **Codebase**: Expect some rough edges—unpolished code, potential bugs, or bits that might need tweaking to run.
+- **Maintenance**: I’ll review issues and PRs as quickly as I can, though you may have to wait a little while until I can get to it
+
+## How to Contribute
+
+If you’d like to contribute:
+
+1. **Fork the Repository**: Make your own copy to work on.
+2. **Make Changes**: Fix bugs, add features, or whatever you wish
+3. **Test if You Can**: No big testing demands, but a quick check that it works is great.
+4. **Submit a Pull Request**: Send a PR with a short note about your changes. I’ll check it out when I can.
+
+I don’t usually enforce strict coding styles or commit rules (though some projects use git-commit hooks), and I may tweak things during merge to match as appropriate.
+## Contribution Ideas
+
+I’m open to things like:
+
+- Bug fixes or stability tweaks.
+- New features or additions.
+- Doc updates or code cleanup.
+
+## Expectations
+
+As a hobby, this project doesn’t come with guarantees—PRs might not get merged right away, and not every issue will get a quick fix. If something sits for a while, it’s not personal, and you’re welcome to keep building on your fork.
+
+Thanks for considering a contribution!
