+# Copilot Instructions for Element
+
+## General Conventions
+
+- **Always check documentation**: Before making assumptions about APIs, libraries, or tools, consult the official documentation first.
+- **Do not make assumptions and guesses**: When uncertain about implementation details, research or ask rather than guessing.
+- **KISS (Keep It Simple, Stupid)**: Favor simple, straightforward solutions over complex ones.
+- **DRY (Don't Repeat Yourself)**: Avoid code duplication. Extract common functionality into reusable functions or components.
+
+## Code Quality
+
+- Write clear, readable code with descriptive names for variables, functions, and classes.
+- Maintain consistency with the existing codebase style and patterns.
+- Consider maintainability and future developers who will read the code.
