 ## Usage
 
+### Solidity Contracts
+
 ```ts
-import { decode } from "@ethereum-sourcify/bytecode-utils";
+import { decode, AuxdataStyle } from "@ethereum-sourcify/bytecode-utils";
 
 const bytecodeRaw = "0x60806040526004361061003f5760003560e01...7265206c656e677468a2646970667358221220dceca8706b29e917dacf25fceef95acac8d90d765ac926663ce4096195952b6164736f6c634300060b0033"
 
-decode(bytecodeRaw);
+// For Solidity contracts
+decode(bytecodeRaw, AuxdataStyle.SOLIDITY);
 ```

+
+### Vyper Contracts
+
+```ts
+import { decode, AuxdataStyle } from "@ethereum-sourcify/bytecode-utils";
+
+const vyperBytecodeRaw = "0x..."; // Your Vyper contract bytecode
+
+// For Vyper contracts
+decode(vyperBytecodeRaw, AuxdataStyle.VYPER);
+```
+
+**Result example**
+
+```json
+{
+  "integrity": "...",

+  "immutableSize": 256,
+  "vyperVersion": "0.3.10"
 }
 ```
+
+#### Vyper Version Compatibility Notes
+
+Different Vyper compiler versions use different auxdata formats:
+
+- **Before v0.3.5**: Auxdata only contains version information in cbor, without length data after it
+- **v0.3.5 to v0.3.9**: Auxdata includes version and length information in cbor
+- **v0.3.10 to v0.4.0**: Auxdata is stored as a cbor array with version object as last element
+- **v0.4.1 and later**: Auxdata cbor array includes integrity check as first element
