+Script to export a VIP in the form of a gnosis safe tx JSON format.
+
+Before executing this script make sure that:
+
+- The network you want to execute the multisig tx exist in `hardhat.config.ts` configuration
+- The gnosis safe wallet address exists in `getSafeAddress` function in `multisig/helpers/utils.ts`.
+- Make sure that the name of the network in `getSafeAddress` matches the network name in the `hardhat.config.ts` and also `chainID` for this network is correct.
+
+Proceed by executing the following command:
+
+```
+npx hardhat run scripts/createProposal.ts --network <networkName>
+```
+
+After executing the command, enter the needed information for the script.
+Here is example input for exporting an example (`multisig/proposals/sepolia/example.ts`) VIP into a JSON Gnosis Safe format:
+
+```
+npx hardhat run scripts/createProposal.ts --network sepolia
+Number of the VIP to propose (if using gnosisTXBuilder press enter to skip ) =>
+Type of the proposal txBuilder/venusApp/bsc/gnosisTXBuilder => gnosisTXBuilder
+Address of the governance contract (optional, press enter to skip) =>
+Name of tx file (from ./multisig/network(available)/ dir) to execute => example
+```
+
+The script should output a file `gnosisTXBuilder.json` that you can import in your Gnosis Safe UI.
