+# Neovim Configuration
+
+A modern Neovim configuration using lazy.nvim for plugin management.
+
+## Installation
+
+1. Make sure you have Neovim 0.8+ installed
+2. Clone or copy the `init.lua` file to your Neovim configuration directory:
+   ```bash
+   # For Linux/macOS
+   cp init.lua ~/.config/nvim/
+   
+   # Or if using this directory structure
+   # The init.lua is already in ~/.vim/
+   ```
+
+3. Start Neovim - lazy.nvim will automatically install all plugins on first launch
+
+## Plugins Included
+
+- **lazy.nvim** - Plugin manager
+- **CtrlP** - Fuzzy file finder (`<Ctrl-P>` to open)
+- **lualine** - Modern status line
+- **gitsigns** - Git change indicators
+- **indent-blankline** - Visual indent guides
+- **bufferline** - Tab-like buffer management
+- **tokyonight** - Beautiful colorscheme
+- **todo-comments.nvim** - TODO comment highlighting
+
+## Key Features
+
+- Line numbers and relative line numbers enabled
+- Syntax highlighting enabled
+- 2-space indentation
+- Smart case searching
+- True color support
+- Git integration with visual indicators
+
+## Usage
+
+### File Navigation
+- `<Ctrl-P>` - Open CtrlP fuzzy finder
+- `:e filename` - Open file
+- `:bn` / `:bp` - Next/previous buffer
+
+### Git
+- Git changes are automatically highlighted in the gutter
+- `+` for additions, `~` for changes, `_` for deletions
+
+### TODO Management
+The configuration highlights TODO comments in your code:
+- `TODO:`, `FIXME:`, `HACK:`, `WARN:`, `PERF:`, `NOTE:`, `TEST:`
+
+## Customization
+
+Edit `init.lua` to customize:
+- Plugin configurations
+- Key mappings
+- Neovim settings
+- Colorscheme options
+
+## Troubleshooting
+
+If plugins don't load:
+1. Check Neovim version: `:version`
+2. Check plugin status: `:Lazy`
+3. Update plugins: `:Lazy update`
+4. Check for errors: `:messages`
