README.md

@@ -5,13 +5,25 @@ A Minecraft Forge mod that provides enhanced teleportation functionality. Easily
 ## Features
 
 - **Simple Commands**: Easy-to-use commands for teleporting players
+- **Riding Entity Teleportation**: When teleporting while riding a living entity (horse, pig, etc.), both player and mount are teleported together
 - **No Dependencies**: This mod does not require any additional libraries or mods to function
 
 ## Usage
 
 Run the following commands in-game:
 - `/tlp <player>`: Teleports you to the specified player.
 
+### Riding Entity Teleportation
+When you use `/tlp` while riding a living entity (such as a horse, pig, donkey, mule, llama, camel, or strider), both you and your mount will be teleported together to the destination. The riding relationship is maintained after teleportation.
+
+**Supported Living Entities:**
+- Horses, Donkeys, Mules
+- Pigs, Striders  
+- Llamas, Camels
+- Any other rideable living entities
+
+**Note:** Non-living vehicles like boats and minecarts are not teleported - only the player will be teleported in these cases.
+
 **Note**: This mod is not recommended for use on PvP servers as it may provide unfair advantages.
