adding flavor how to

I ma planing to bre my second badge of hefewizen but this time I will like to add a touck of mango . I am confuse on
1: should I add it when making the worth?
2 should I add it after cool down in the first fermentation

Also for 5 gallosn what should be a proper ratio.

the goal is tho have a twist in the flavor not to have a Mango beer

two options come to mind.

1. Use the mango rind instead of the mango fruit itself.
2. Use mango juice in secondary.

if you don't want mango to take over your beer, you're going to have to avoid using a lot of mango juice. that's why i think the mango rind may add the essence of mango without making your beer a mango beer. but, with all those fermentables in the sweetness of the mango itself, it wouldn't be a bad idea to add a tiny bit of juice instead of sugar at bottling/kegging for another mango dynamic.
