+## Multisig Usage
+
+> [!WARNING]  
+> Safe Multisig Wallet is not currently supported in Holesky Testnet.
+
+You can create a Multisig wallet using [Safe](https://safe.global/).
+
+Once you have a Multisig, you can deploy the contracts using the Multisig wallet address as the upgrader, pauser, etc.
+
+In order to upgrade a contract using the Multisig, you have to run:
+
+```bash
+make upgrade_aligned_contracts
+```
+
+Then, if the new implementation is correctly deployed, the script will show the following message:
+
+```bash
+You can propose the upgrade transaction with the multisig using this calldata
+<calldata>
+```
+
+You can use this calldata to send the transaction using the Multisig wallet in the transaction builder provided by Safe
+

+
+For example, if you are upgrading the ServiceManager, fill the data with the ProxyAdmin address and ABI
+
+To get the ProxyAdmin address for Holesky you can run
+
+```bash
+jq -r ".addresses.alignedLayerProxyAdmin" contracts/script/output/holesky/alignedlayer_deployment_output.json | pbcopy
+```
+
+To get the ABI you can run
+
+```bash
+jq ".abi" contracts/out/ProxyAdmin.sol/ProxyAdmin.json | pbcopy
+```
+
+Then, you can paste the ABI in the ABI field

+
+If the transaction is correctly created, you have to wait until required Multisig member sign the transaction to send it
