+# Contributing
+
+Thanks for your interest in contributing. Please follow these guidelines to keep the project consistent and maintainable in the long-term.
+
+## Vision
+
+- This is a simple text-based interface. Follow the [KISS principle](https://en.wikipedia.org/wiki/KISS_principle) – keep the code simple and easy to maintain, abstractions minimal, and the API easy to use without reading a manual.
+- Don't run any logic if the console is closed or hidden.
+
+## Code Style & Recommendations
+
+- Follow the official [GDScript Style Guide](https://docs.godotengine.org/en/stable/tutorials/scripting/gdscript/gdscript_styleguide.html).
+- Use [static typing](https://docs.godotengine.org/en/stable/tutorials/scripting/gdscript/static_typing.html) wherever possible.
+- Apply the 80/20 rule: if a feature only benefits a small number of users, make it optional or don’t include it.
+- To avoid unnecessary whitespace changes, please enable this setting in Godot: `Editor Settings > Text Editor > Behavior > Files > Trim Trailing Whitespace on Save`
