+# How to contribute
+
+👍🎉 First off, thanks for taking the time to contribute! 🎉👍
+
+The following is a set of guidelines for contributing to this component.
+These are mostly guidelines, not rules.
+Use your best judgment, and feel free to propose changes to this document in a pull request.
+
+## Note
+
+Writing code and suggesting fixes is not the only way to contribute!  
+Your comments, problems, and opinions posted in [Discussion](https://github.com/hrntsm/HoaryFox/discussions) or [Issues](https://github.com/hrntsm/HoaryFox/issues) are one aspect of contribution.
+
+Feel free to post it.
+
+## Submitting changes
+
+Please send a [GitHub Pull Request](https://github.com/hrntsm/HoaryFox/pull/new/main) with a clear list of what you've done (read more about [pull requests](http://help.github.com/pull-requests/)).
+When you send a pull request, we will love you forever if you include examples.
+Please follow our coding conventions (below) and make sure all of your commits are atomic (one feature per commit).
+
+Always write a clear log message for your commits. One-line messages are fine for small changes, but bigger changes should look like this:
+
+    $ git commit -m "A brief summary of the commit
+    >
+    > A paragraph describing what changed and its impact."
+
+## Coding conventions
+
+Start reading our code and you'll get the hang of it.
+Please check your .editorconfig file and code accordingly and format it with `dotnet format` commands.
+
+Thanks,
+hrntsm
