-# System Patterns: Neovim Configuration
+# System Patterns
 
 ## System Architecture
-1. **Core Configuration Structure**
-   - init.lua as main configuration file
-   - Lazy plugin management system
-   - LSP integration through nvim-lspconfig
-   - Custom keymaps and settings
+1. Configuration Layer Design
+   - Core configuration (init.lua)
+   - Module-based organization
+   - Plugin management system
+   - User customization layer
 
-2. **Key Components**
-   - Plugin Management (lazy.nvim)
-   - LSP Configuration
-   - Treesitter Integration
-   - Diagnostic System
-   - Custom Keybindings
+2. Feature Organization
+   - LSP services management
+   - Completion engine integration
+   - File tree and navigation
+   - Buffer and window management
+
+3. Event System
+   - Autocommands framework
+   - Key mapping system
+   - Plugin hooks
+   - Custom events
 
 ## Key Technical Decisions
+1. Plugin Management
+   - Use of lazy.nvim for plugin management
+   - Lazy-loading strategy for performance
+   - Conditional plugin loading
+   - Dependencies management
 
-### Plugin Management
-- Using lazy.nvim for plugin management
-- Lazy loading enabled for better startup performance
-- Plugin-specific configurations contained within setup blocks
+2. LSP Implementation
+   - Native LSP client usage
+   - Mason.nvim for LSP server management
+   - Language-specific configurations
+   - Diagnostic system integration
 
-### LSP Implementation
-- Mason for LSP server management
-- nvim-lspconfig for LSP configuration
-- Custom LSP attach events and keymaps
-- Diagnostic configuration through vim.diagnostic
+3. Performance Optimization
+   - Modular loading system
+   - Cache implementation
+   - Startup optimization
+   - Memory management
 
-### Editor Features
-- Treesitter for syntax highlighting
-- Telescope for fuzzy finding
-- Which-key for keymap discovery
-- Mini.nvim for various utilities
+## Architecture Patterns
+1. Module Pattern
+   ```lua
+   -- Module structure
+   local M = {}
+   -- Configuration
+   M.setup = function(opts)
+     -- Setup logic
+   end
+   -- Module functions
+   M.function_name = function()
+     -- Implementation
+   end
+   return M
+   ```
 
-## Component Relationships
-1. **Plugin Dependencies**
-   - LSP plugins depend on nvim-lspconfig
-   - UI elements depend on having Nerd Font
-   - Telescope depends on plenary.nvim
+2. Plugin Setup Pattern
+   ```lua
+   -- Plugin configuration pattern
+   {
+     "plugin/name",
+     event = "Event",
+     dependencies = {},
+     config = function()
+       require("plugin").setup({})
+     end
+   }
+   ```
 
-2. **Configuration Flow**
-   - Leader key set before plugins
-   - Basic options configured early
-   - Plugins loaded through lazy.nvim
-   - LSP servers configured after plugins
-   - Keymaps set after all configurations
+3. LSP Configuration Pattern
+   ```lua
+   -- LSP server setup pattern
+   lspconfig[server].setup({
+     capabilities = capabilities,
+     on_attach = on_attach,
+     settings = {}
+   })
+   ```
 
-## Design Patterns
-1. **Modularity**
-   - Separate plugin configurations
-   - Isolated LSP server settings
-   - Independent keymap definitions
+## Implementation Guidelines
+1. Code Organization
+   - One feature per file
+   - Clear module interfaces
+   - Consistent naming conventions
+   - Documentation standards
 
-2. **Event-Driven**
-   - LSP attach events
-   - Autocommands for specific behaviors
-   - Lazy loading based on events
+2. Configuration Standards
+   - User-facing options
+   - Default values
+   - Type checking
+   - Validation
+
+3. Error Handling
+   - Graceful degradation
+   - User feedback
+   - Debug logging
+   - Recovery mechanisms
+
+## System Components
+1. Core Components
+   - Plugin manager
+   - LSP client
+   - Completion engine
+   - File explorer
+
+2. Language Support
+   - LSP servers
+   - Treesitter parsers
+   - Language tools
+   - Formatters
+
+3. UI Components
+   - Status line
+   - Buffer line
+   - Command line
+   - Notifications
+
+4. Integration Layer
+   - Git integration
+   - Terminal
+   - Debug adapter
+   - External tools
