Decide on the amount of USDC to spend to enter ETH, put this in `amountUSDC`. \n2. Set your upper and lower price ranges in `upperPrice` and `lowerPrice`. \n3. Put your wallet address as the `delegator` so that the workflow can execute DCA buys on your behalf. \n4. Set the Telegram chatID for your bot to receive notifications.\n\n### Optional Parameters\nIf you want to change the chain or assets you may have to change these parameters:\n\n1. Set the correct address for the Uniswap [SwapRouter](https://docs.uniswap.org/contracts/v3/reference/deployments/) contract\n2. If you want to trade something besided ETH/USDC, you'll need to set the correct addresses for `token0`, `token1`, `token0Decimals` and `token1Decimals`.\n3. Check the `fee` for the pool you are targeting and make sure it matches. \n4. Edit the slippage percentage to your taste. "
