+
+## what is this?
+A simple deposit and profit bytom dapp demo, Bytom-Chrome-Extension needed before it can be used. 
+
+
+## Setup
+Make sure you have the NodeJs installed before you started.
+start the webpack dev server:
+
+```
+npm start
+```
+Your server should now be running at http://127.0.0.1:8080 
+
+### Contract configuration
+Network and smart contract control program's constants configurations are stored under the `contracts/configure.json.js` file.
 You may edit the configure after an new control program is launched.
 
-### Send transaction
-After the banker deploy the FixedLimitCollect smart contract. The users can use the dapp demo to build an input and output object. 
-Send an smart contract transaction based on the either [Deposit smart contract](https://github.com/Bytom/equity/blob/master/compiler/equitytest/FixedLimitCollect)
- or [Profit smart contract](https://github.com/Bytom/equity/blob/master/compiler/equitytest/FixedLimitProfit).
- 
-### Injection of Chrome-Extension
-Since the [chrome-extension](https://github.com/Bytom/Bystore) injected the global bytom into the window. 
-Use the `window.bytom.advancedTransfer` to send a transaction. Note that `window.bytom.advancedTransfer` contain
-`buildTx`, `signTx` and `submitTx`.
+*Note: Currently we are manually deploy the contract using the [equity compiler tool](https://github.com/Bytom/equity), and configure the constants accordingly.
+
+### Input and Output Object
+Since the contract type and logic are different, building the unlock action may be different.
+
+```
+if amountDeposited < billAmount {
+      lock amountDeposited of assetDeposited with FixedLimitProfit(billAsset, totalAmountBill, totalAmountCapital, expireBlockHeight, additionalBlockHeight, banker, bankerKey)
+      lock amountDeposited of billAsset with saver
+      lock billAmount-amountDeposited of billAsset with FixedLimitCollect(assetDeposited, totalAmountBill, totalAmountCapital, dueBlockHeight, expireBlockHeight, additionalBlockHeight, banker, bankerKey)
+    } else {
+      lock amountDeposited of assetDeposited with FixedLimitProfit(billAsset, totalAmountBill, totalAmountCapital, expireBlockHeight, additionalBlockHeight, banker, bankerKey)
+      lock billAmount of billAsset with saver
+    }
+```
+Will need to be converted into
+```
+ if(amount < billAmount){
+          output.push(controlProgramAction(amount, GetContractArgs().assetDeposited, GetContractArgs().profitProgram))
+          output.push(controlAddressAction(amount, billAsset, address))
+          output.push(controlProgramAction((BigNumber(billAmount).minus(BigNumber(amount))).toNumber(), billAsset, GetContractArgs().depositProgram))
+        }else{
+          output.push(controlProgramAction(amount, GetContractArgs().assetDeposited, GetContractArgs().profitProgram))
+          output.push(controlAddressAction(billAmount, billAsset, address))
+        }
+```
+
+## Building the Project
