I am quite beginner to solidity, trying to learn smart contracts.

so here in this fees code:

bool autoLiquifyEnabled = true;
uint256 liquidityFee = 600;
uint256 liquidityFeeAccumulator;

uint256 buybackFee = 0;
uint256 reflectionFee = 400;
uint256 marketingFee = 500;
uint256 devFee = 0;
uint256 totalFee = 1000;
uint256 feeDenominator = 10000;
if I want let's say to set 10% fees, 2% to lp, 4% marketing, and 4% reflections, should I do it this way?

bool autoLiquifyEnabled = true;
uint256 liquidityFee = 200;
uint256 liquidityFeeAccumulator;

uint256 buybackFee = 0;
uint256 reflectionFee = 400;
uint256 marketingFee = 400;
uint256 devFee = 0;
uint256 totalFee = 1000;
uint256 feeDenominator = 10000;
and can someone explain what each line do there? Thanks!
