To remove liquidity from a pool, navigate to the portfolio page and click on the current LP position that you would like to remove.
Navigate to the Withdraw tab in the pool page.
Select the percentage of liquidity you would like to withdraw then press the "Approve" and "Confirm" buttons. You can also set a Slippage amount similar to the Trade Page and the Depositing Liquidity option on the Pool Page. Simply select the "Gear Icon" and input a slippage amount.
You will get a wallet confirmation to approve the token allowance and then to confirm the transaction. Accept both wallet confirmations when they pop up.
