-```
-use .mainnet.empty.json as initial file to update contracts information while deploy
-
-define env value
-
-FORK_RPC_URL=<fork rpc url>
-IMPERSONATE_ACCOUNT=<impersonate address>
-```
-
-note
-```
-if found `failed ProviderError: resource not found` try remove `.mainnet.json` in `.openzeppelin`

-1. run `yarn compile` if contracts is already compiled with stabled code, you can skip this step
-2. run `yarn deploy:aldex-core`\
-   deploy Libraries, AldexDeployer, AldexBank, Ausd, AldexBankConfig, ConcentratedLiquidityPoolFactory, etc..
-3. run `yarn deploy:oracle`\
-   deploy ChainlinkPriceOracle, OracleChecker, setChainlinkPriceOracle on AldexBankConfig, setOracleChecker on AldexBank
-4. run `yarn deploy:strategy-outside-swap`\
-   deploy UniswapV3StrategyOutsideSwap and whitelist on AldexBank
-5. run `yarn deploy:concentrated-pool`\
-   deploy cl pools with custom inputs variable inside `concentrated-liquidity-pool.ts`
-6. run `yarn deploy:concentrated-pool-helper`
