Adding Liquidity pool to pancakeswap


I’ve created my ERC20 token with totalSupply of 1000000000000000 and I want to burn 50% of the coin and set the initial price 10BNB : 1000000000000 (0.1%) at Pancakeswap.

My question is what should I do with the rest of the coins? Should I refill the liquidity with the rest or what is recommend?
