+# Instructions
+
+## Context
+- User maintains a literate Emacs configuration using Org-mode
+- Configuration is tangled from `emacs.org` to `~/.emacs.d/init.el`
+- User prefers minimal, clean code with good documentation
+- Running NixOS system with declarative package management
+
+## Emacs/Org-mode Preferences
+- Always use `use-package` for package configuration
+- Include `:ensure t` for external packages
+- Add descriptive comments explaining configuration choices
+- Use org-babel for literate programming approach
+- Prefer built-in Emacs features when possible
+
+## Code Style
+- Use semicolon comments for Emacs Lisp: `;;`
+- Namespace custom functions with `geokkjer/` prefix
+- Keep code blocks focused and single-purpose
+- Include installation checks: `(unless (package-installed-p 'pkg)...)`
+
+## File Organization
+- Group related configurations under logical headings
+- Use `** Subsection` for major feature areas
+- Include explanatory text before each code block
+- Maintain consistent indentation and formatting
+
+## When Suggesting Changes
+- Always show complete org-mode code blocks with proper syntax
+- Include the `#+BEGIN_SRC emacs-lisp` and `#+END_SRC` markers
+- Explain what the configuration does and why it's useful
+- Mention tangling requirement after changes
+
+# domain knowledge
+- Familiar with Emacs Lisp and Org-mode syntax
+- Understands NixOS package management
+- Knows how to use `use-package` for package management
+- Comfortable with literate programming concepts
+- Values clean, maintainable code with good documentation
+- Prefers a functional programming style
+- Appreciates modular and reusable code structures
