-# Product Context: Neovim Configuration
+# Product Context: Neovim IDE Configuration
 
 ## Why This Project Exists
-This Neovim configuration exists to provide a robust, maintainable development environment based on the Kickstart.nvim template. It aims to deliver modern editor features while maintaining simplicity and transparency in its implementation.
+This project aims to transform Neovim into a powerful, fully-featured Integrated Development Environment (IDE) that provides modern development capabilities while maintaining Neovim's core efficiency and extensibility. It serves developers who want the speed and flexibility of Neovim combined with the comprehensive features of traditional IDEs.
 
 ## Problems It Solves
-1. **Module Accessibility**: Currently addressing issues with runtime file locations and module loading, specifically the vim.diagnostic module
-2. **Development Environment**: Provides a comprehensive IDE-like environment through:
-   - LSP integration for code intelligence
-   - Treesitter for advanced syntax highlighting
-   - Fuzzy finding and file navigation
-   - Git integration
-   - Diagnostic capabilities
+1. Development Environment Integration
+   - Fragmented development tooling
+   - Inconsistent development experiences across languages
+   - Complex setup requirements for different programming languages
+   - Need for multiple editors/IDEs for different tasks
+   - Debugging Tools
+
+2. Productivity Barriers
+   - Manual code completion and navigation
+   - Lack of integrated debugging capabilities
+   - Inefficient project management
+   - Limited language support
+
+3. Configuration Management
+   - Complex plugin management
+   - Inconsistent keybindings
+   - Difficult maintenance of settings
+   - Performance optimization challenges
 
 ## How It Should Work
-1. **Runtime Environment**:
-   - All Neovim runtime files should be properly located and accessible
-   - Core modules like vim.diagnostic should load without errors
-   - VIMRUNTIME environment variable should point to correct location
 
-2. **User Experience**:
-   - Configuration should load without errors
-   - All plugins should initialize properly
-   - LSP features should work seamlessly
-   - Diagnostic information should be visible and accurate
+### Language Support
