IN 5-10 PLO or Pot Limit anything, the opening raise will be 3 times the big blind + whatever else is in the pot, so in 5-10 you can raise it to between 20 and 35. If two people call the 10 in front of you, you can make it up to 55. In pot limit you can either bet the amount in the pot, or, if you want to raise it is always 3 times the previous bet times whatever else is in the pot. Preflop it is considered a raise and therefore the 3x raise+ pot comes into play.
