+/**
+ * @title Prepare ZKChain Registration Calldata
+ * @dev Script to prepare calldata for registering a new ZKChain on the bridgehub
+ *
+ * This script prepares calldata for registering a new ZKChain on the bridgehub
+ * That includes 3 steps:
+ * 1. Register base token on the bridgehub
+ * 2. Register the new ZKChain on the bridgehub
+ * 3. Initialize the L2 bridge on the L1 shared bridge
+ *
+ * The script precomputes the address of the L2 bridge to generate the calldata for the third step.
+ * It assumes that L1 governance is the owner of the L2 bridge and the L2 bridge is deployed by the msg.sender of the script.
+ *
+ * The script reads the configuration from a TOML file `script-config/prepare-registration-calldata.toml`
+ * and writes the output to a TOML file `script-out/output-prepare-registration-calldata.toml`.
+ *
+ * The output contains 4 fields:
+ * - scheduleCalldataStageOne: calldata for scheduling the first stage
+ * - executeCalldataStageOne: calldata for executing the first stage
+ * - scheduleCalldataStageTwo: calldata for scheduling the second stage
+ * - executeCalldataStageTwo: calldata for executing the second stage
+ * (stage 2 of the execution is the registration of the L2 bridge on the L1 shared bridge)
+ *
+ * The separation is required to ensure that there is no period of time where the L2 bridge is registered, so users
+ * can send their funds there, but they will be burned in case L2 bridge is not initialized by the chain operator.
+ * It is meant to be executed only after the L2 bridge is deployed.
+ *
+ * How to use:
+ * 1. Create a TOML file `script-config/prepare-registration-calldata.toml`, reference config at `deploy-script-config-template/config-prepare-registration-calldata.toml`.
+ * 2. Run the script impersonating the address that will deploy the L2 bridge, `forge script --rpc-url $RPC --sender $DEPLOYER PrepareZKChainRegistrationCalldata.s.sol`
+ * 3. Run the `scheduleCalldataStageOne` and `executeCalldataStageOne` on the L1 chain using governance.
+ * 4. Deploy the L2 bridge using the address from step 2. This address doesn't need any special permissions, just has to be consistent across all the stages.
+ * 5. Run the `scheduleCalldataStageTwo` and `executeCalldataStageTwo` on the L1 chain using governance.

 Chain migration uses the Custom Asset Bridging framework:
 
-- STMs can be deployed on the Gateway. Each STM has its own assetId.
-- The STM Deployment Tracker deployed on L1 registers assetId in the L1 and L2 AssetRouters, with the Bridgehub as the AssetHandler. It also registers the L1 and L2 STM contracts to be associated to the assetId in the Bridgehubs.
-- Bridging of a chain happens via the Bridgehub, AssetRouters, and STM.
