+# čd (České dráhy)
+
+A fun terminal animation of a Czech Railways motorak (railcar) - the Czech version of the classic `sl` command.
+
+```

+    \_O_/  \_O_/   \_______/     \_O_/  \_O_/
+
+        České dráhy - Motorák 810
+```
+
+Inspired by the legendary `sl` command, but featuring the iconic ČD Class 810/810.0 "Orchestrion" motorak.
+
+## Installation
+
+### From AUR (Arch Linux)
+
+```bash
+yay -S cd-czechrailways
+# or
+paru -S cd-czechrailways
+```
+
+### Manual Installation
+
+```bash
+git clone https://github.com/YOUR_USERNAME/ceskadráha.git
+cd ceskadráha
+sudo make install
+```
+
+### Manual (without make)
+
+```bash
+sudo cp čd /usr/local/bin/
+sudo chmod +x /usr/local/bin/čd
+```
+
+## Usage
+
+```bash
+čd           # Run the animation (left to right)
+čd -r        # Run in reverse (right to left)
+čd -h        # Show help
+```
+
+## Features
+
+- Animated Czech Railways Class 810 motorak
+- Reverse direction support
+- Animated exhaust/smoke
+- Terminal width aware
+- Thank you message in Czech: "Děkujeme, že jste cestovali s Českými drahami!"
+
+## Why?
+
+Just like the original `sl` command was created to punish users who mistype `ls`, this is for Czech railway enthusiasts who want a bit of fun in their terminal. Or maybe you just really like Czech motoráks.
+
+## Requirements
+
+- Bash
+- `tput` command (usually part of ncurses)
+
+## License
+
+MIT License - See LICENSE file for details
+
+## Credits
+
+Inspired by the classic `sl` (Steam Locomotive) command by Toyoda Masashi.
