In the process of adding liquidity, a user decides to deposit tokens to the liquidity pool. This helps to maintain a better exchange rate stability (reduces slippage). As a result, he receives a portion of swap fees as a reward.
Liquidity providers receive LP tokens (liquidity provider tokens) in return for locking in their tokens. These tokens represent the size of the provider's share in the liquidity pool and can be redeemed at any time for the deposited tokens. The value of individual LP tokens grow as swap fees are accumulated in the pool and the value is also impacted by an impermanent loss if the exchange rate changes significantly.
A good thing to keep in mind when adding liquidity is that the amount of received LP tokens is dependent on the ratio in which the liquidity is provided. The ratio is automatically calculated by the UI to provide liquidity providers with the maximum possible amount of LP tokens they are eligible for. However, especially in the smaller pools, the asset ratio can significantly change and impact the number of received LP tokens. Therefore, liquidity providers can specify LP token slippage percentage in the Transaction settings to ensure that their requests won't get executed in case they would've received fewer tokens than they expect.

You can find the option to add liquidity in the Pool tab. Here you can filter the desired pool using the provided filter text field.
After clicking on the Add Liquidity button, a Manage liquidity form will appear. You want to have selected the Add liquidity option. Here you input one of the amounts. The other one will be automatically calculated based on the most recent exchange rate.
To access the Transaction settings, click the ⚙️ button. There you will find the option to adjust the slippage tolerance and deadline.
To see a more detailed breakdown of all the fees and assets, click the Total fees button.
Once you are ready, click Add Liquidity. WingRiders will let you once more review the transaction details. If you are satisfied with the transaction, confirm it using the Confirm button. Afterwards, you will be prompted by your connected wallet to sign the transaction (example from Nami Wallet, interface may differ in other wallets).
After successfully signing the transaction, WingRiders will inform you about a successful add liquidity request submission. You can track progress of your request in the Transactions tab, either by clicking Transaction list in the message window or you can click Transactions in the top right corner.
After successful execution, you will see that swap listed in the Completed tab.
