-## How to modify emissions of the LM program?
+3. Create a payload with the call of EMISSION_MANAGER.
 
-The function `_getEmissionsPerAsset()` on [EmissionTestOpOptimism.t.sol](./tests/EmissionTestOpOptimism.t.sol) defines the exact emissions for the particular case of $OP as reward token and a total distribution of 5'000'000 $OP during exactly 90 days.
-The emissions can be modified there, with the only requirement being that `sum(all-emissions) == TOTAL_DISTRIBUTION`

-You can run the test via `forge test -vv` which will emit the selector encoded calldata for `configureAssets` on the emission admin which you can use to execute the configuration changes e.g. via Safe.
+      emissionPerSecond: 60000 * 1e18 / (180 days in seconds)
 
-_Note: The test example above uses total distribution and duration distribution just for convenience to define emissions per second, in reality as we only pass emissions per second to `configureAssets()` we could define it in any way we wish._
+      totalSupply: 0
 
-## How to configure emissions after the LM program has been created?
+      distributionEnd: current timestamp + (180 days in seconds)
 
-After the LM program has been created, the emissions per second and the distribution end could be changed later on by the emissions admin to reduce the LM rewards or change the end date for the distribution. This can be done by calling `setEmissionPerSecond()` and `setDistributionEnd()` on the Emission Manager contract. The test examples on [EmissionConfigurationTestMATICXPolygon.t.sol](./tests/EmissionConfigurationTestMATICXPolygon.t.sol) shows how to do so.
+      asset: Aave Variable Debt Token of wMatic // 0x4a1c3aD6Ed28a636ee1751C69071f6be75DEb8B8
 
-The function `_getNewEmissionPerSecond()` and `_getNewDistributionEnd()` defines the new emissions per second and new distribution end for the particular case, which could be modified there to change to modified emissions per second and distribution end.
+      reward: MaticX Token address // 0xfa68FB4628DFF1028CFEc22b4162FCcd0d45efb6
 
-Similarly you can also run the test via `forge test -vv` which will emit the selector encoded calldata for `setEmissionPerSecond` and `setDistributionEnd` which can be used to make the configuration changes.
+      transferStrategy: ITransferStrategyBase(STRATEGY_ADDRESS) // 0x53F57eAAD604307889D87b747Fc67ea9DE430B01
+
+      rewardOracle: IEACAggregatorProxy(MaticX_ORACLE_ADDRESS) // 0x5d37E4b374E6907de8Fc7fb33EE3b0af403C7403
+
+    }])
+    ```
+
+4. Submit a proposal in the Permissioned Payloads Controller with the Payloads Manager:
+
+    ```
+    PERMISSIONED_PAYLOADS_CONTROLLER.createPayload([{
+
+      target: EMISSION_MANAGER,
+
+      withDelegateCall: false,
+
+      accessLevel: PayloadsControllerUtils.AccessControl.Level_1,
+
+      value: 0,
+
+      signature: "",
+
+      calldata: payload
+
+    }])
+    ```
+
+## How to update an existing LM program
+
+The process to update the existing LM program is quite similar to the explained LM setup process. The difference from the previous process is that you need to use the `setDistributionEnd()` and `setEmissionPerSecond()` functions instead of the `configureAssets()` function of the Emission Manager. Payloads received after encoding calls of these functions in the same way need to be passed to the `createPayload()` function of the Permissioned Payloads Controller to create a proposal.
+
+## Configuration tools
+
+This repository includes a generator to help you bootstrap the required files for an emission configuration. To generate an LM configuration proposal, you need to run `npm run generate`. It can generate either LM setup or LM update proposal.
+
+As a result you'll receive helper files similar to [PermissionedControllerEmissionTestMATICXPolygon](tests/PermissionedControllerEmissionTestMATICXPolygon.t.sol) and [PermissionedPayloadsControllerAndExecutorDeploy](scripts/EmissionMATICXPolygonConfigurationDeploy.s.sol). The first file is test file, it can help you to validate your configuration. Once the configuration is validated you can deploy your proposal using the second file. All required scripts you'll find inside these files.
+
+To get a full list of available commands, run `npm run generate -- --help`.
 
 ## FAQ's:
 
 - Do we need to have and approve the whole liquidity mining reward initially?
 
-  It is generally advisable to have and approve funds for the duration of the next 3 months of the Liquidity Mining Program. However it is the choice of the Emission Admin to do it progressively as well, as the users accrue rewards over time.
