+# Modifying the Swaparoo Smart Contract
+
+To modify the `swapWithFee` contract so that the fee is doubled, you need to use the parameter governance features provided by the Agoric platform. Here's how you can do it:
+
+### Update the contract code to support parameter governance:
+- Import the necessary functions from `@agoric/governance/src/contractHelper.js`.
+- Define the parameter types for the governed parameters (in this case, `Fee`).
+- Modify the `start` function to include `handleParamGovernance` and get the `publicMixin`, `makeDurableGovernorFacet`, and `params`.
+- Update the `publicFacet` and `creatorFacet` to include the `publicMixin` and `makeDurableGovernorFacet`.
+- Deploy the updated contract code and start the contract instance.
+
+### Set up the committee (electorate) and election manager contracts:
+- Deploy the `committee.js` contract from `@agoric/governance` for the electorate.
+- Deploy the `econCommitteeCharter.js` contract from `@agoric/inter-protocol` for the election manager.
+- Obtain invitations for the committee members and send them to their smart wallets.
+
+### Committee members accept the charter and committee invitations:
+- Each committee member uses their smart wallet to redeem the charter invitation and obtain the capability to put a question using `VoteOnParamChange`.
+- Each committee member also accepts the committee invitation to obtain the capability to vote.
+
+### A committee member puts a question to double the fee:
+- The committee member creates an offer with the necessary `offerArgs`, including the new fee value (doubled) and the deadline.
+- The offer is made using the `VoteOnParamChange` capability obtained earlier.
+
+### Other committee members vote on the question:
+- Each committee member retrieves the question details from `vstorage` using the `questionHandle`.
+- They create an offer to vote on the question using the `makeVoteInvitation` capability obtained earlier.
+
+### Once the deadline is reached and the question carries, the contract governor is notified:
+- The contract governor instructs the `swapWithFee` contract to change the fee to the new value (doubled).
+- The `swapWithFee` contract updates its parameters and publishes the changes to `vstorage`.
+
+By following these steps and utilizing the parameter governance features provided by Agoric, you can modify the `swapWithFee` contract to double the fee without directly changing the contract code. The changes are made through a governed process involving the committee members and the election manager.
