+:PlugInstall
+:PlugUpdate
+```
+
+### Autocomplete not working?
+
+Make sure Node.js is installed:
+```bash
+node --version  # Should be >= 14.14
+```
+
+Then install CoC language servers:
+```vim
+:CocInstall coc-json coc-tsserver coc-pyright
+```
+
+### FZF not finding files?
+
+Install FZF and ripgrep:

+
+# macOS
+brew install fzf ripgrep
+```
+
+### Colors look weird?
+
+Add to your `~/.bashrc` or `~/.zshrc`:
+```bash
+export TERM=xterm-256color
+```
+
+## Customization
+
+The `.vimrc` file is well-organized into sections:
+
+1. **General Settings** (lines 1-150) - Basic Vim behavior
+2. **Plugin Management** (lines 151-230) - Plugin list
+3. **Key Mappings** (lines 300-400) - Custom shortcuts
+4. **Plugin Settings** (lines 400-600) - Plugin configurations
+
+To customize:
+1. Open `~/.vim/.vimrc`
+2. Find the section you want to modify
+3. Make your changes
+4. Reload with `:source ~/.vimrc` or restart Vim
+
+### Common Customizations
+
+**Change colorscheme:**
+```vim
+" In .vimrc, find the colorscheme line and change to:
+colorscheme dracula
+" or: solarized, onedark, gruvbox
+```
+
+**Change leader key:**
+```vim
+" Default is comma (,), change to space:
+let mapleader = " "
+```
+
+**Disable relative line numbers:**
+```vim
+set norelativenumber
+```
+
+## Next Steps
+
+1. Read the full [README.md](README.md) for complete documentation
+2. Check out `:help` in Vim for built-in documentation

+
+```vim
+" .vimrc in project root
+set shiftwidth=2
+let g:ale_python_black_options = '--line-length=100'
+```
+
+The configuration automatically loads project-specific settings while maintaining security.

+### Session Management
+
+Sessions are automatically saved with vim-obsession:

+```vim
+" Start session tracking
+:Obsess
+
+" Stop session tracking
+:Obsess!
+
+" Sessions are saved to ~/.vim/sessions/

+### Large File Handling
+
+Files larger than 10MB automatically disable heavy features for better performance:
+- Syntax highlighting optimized
+- Undo levels reduced
+- Swap files disabled
+
+### Terminal Integration

+Open integrated terminal:
+- `,tv` - Vertical terminal split
+- `,th` - Horizontal terminal split (10 rows)
