+#### Python
 ```shell
 stellar-contract-bindings python --contract-id CDOAW6D7NXAPOCO7TFAWZNJHK62E3IYRGNRVX3VOXNKNVOXCLLPJXQCF --rpc-url https://mainnet.sorobanrpc.com --output ./bindings
 ```
 
-This command will generate Python binding for the specified contract and save it in the `./bindings` directory.
+#### Java
+```shell
+stellar-contract-bindings java --contract-id CDOAW6D7NXAPOCO7TFAWZNJHK62E3IYRGNRVX3VOXNKNVOXCLLPJXQCF --rpc-url https://mainnet.sorobanrpc.com --output ./bindings --package com.example
+```

+#### Flutter/Dart
+```shell
+stellar-contract-bindings flutter --contract-id CDOAW6D7NXAPOCO7TFAWZNJHK62E3IYRGNRVX3VOXNKNVOXCLLPJXQCF --rpc-url https://mainnet.sorobanrpc.com --output ./lib --class-name MyContract
+```
