+### TTY and Basic Terminal Support
+
+The configuration automatically detects and optimizes for basic terminal environments (TTY, Linux console):
+
+**Automatic Optimizations:**
+- Disables true color mode for compatibility
+- Uses simple ASCII separators instead of powerline fonts
+- Falls back to default colorscheme
+- Disables cursorline for better performance
+- Simplifies signcolumn behavior
+- Disables FZF preview windows
+- Skips auto-opening NERDTree
+- Uses simpler status line
+- Reduces syntax highlighting complexity
+- Faster startup and redraw
+
+**Detected Terminals:**
+- Linux console (TERM=linux)
+- Screen sessions (TERM=screen)
+- Basic built-in terminals
+
+The configuration provides a message on first run in TTY mode to inform about the optimizations.

 ## Customization
 
 The configuration is organized into sections:
