+* Add multi-signing example to sign() method docs
+* Update TypeScript
+
 ## 1.3.3 (2019-09-10)
 
 * Expand node version compatibility to support Node.js 12 ([ripple-binary-codec#32](https://github.com/ripple/ripple-binary-codec/issues/32))

+
+Assuming the multisigning account was setup properly, the above example will respond with `resultCode: 'tesSUCCESS'` and the hash for the transaction.
+If any of `{signAs: some_address}` options were missing the code will return a validation error as follow:
+```
+[ValidationError(txJSON is not the same for all signedTransactions)]
