From the PumpSwap page, select the "deposit/create" option.
Select "Create".
This is where you will initiate the process of creating a new liquidity pool, or add to an existing one.
Select the tokens for the liquidity pair.
Choose the two tokens that you want to create your pair from.
The first token is going to be your "Quote Token" like SOL, USDC, USDT, or another supported token.
This token is what will defines the price.
The second token is going to be your "Base Token".
This generally is going to be the token that you created or bought.
Set the initial parameters.
Enter the token amounts that you wish to deposit into the liquidity pool.
Initial Price will be determined by the token ratio that you deposit.
Example: Depositing 1 SOL (Quote Token) and 1,000 Token X (Base Token) will mean that buying 1,000 of Token X will cost 1 SOL.
