2: Provide liquidity
Go to "Pool" tab

Same function as before, but if you are doing this for the first time:
1: Provide 50/50 liquidity e.g. ETH/DAI 50/50 ratio with USD price
Not like Balancer pool with AMM (Automated market making)

There was no indication during this step but you will get UNI-V2 XXX-XXX (pair) token

3: Go to "UNI" tab
Deposit liquidity pool token which is given with providing the liquidity into the pool above.  "UNI-V2 ETH-DAI token" in this case
​This is similar to Curve LP token.

​Thanks!
