How to set bonus yields on tiles? [Extremely new to modding]

[bghvgjdh]

So I'm trying to get into some basic modding for this game, and wanting to give a basic production yield to mountain tiles for my first civ; however, I can't seem to find the modifier that should do this? I feel like it must exist since Peter's leader ability does something very similar for tundra.

This is probably an exceedingly obvious solution, so if anyone has any tips for useful guides to look at that can help me get on my feet as well, that would be much appreciated too.

Thanks!

You will need to add a simple mod for this, even if only alters some modifier, try to see this manual: https://forums.civfanatics.com/threads/civ-6-modding-tools-basics.634429/#post-15173204

It's not part of Peter's Leader Ability. It's the Russian Civilization's Ability.

Flatland Tundra tiles and Tundra Hill tiles are workable and are included in the Requirements & Modifiers set-ups for the Mother Russia abilty, but Tundra Mountain tiles are not since Mountain tiles are not workable themselves (though they give adjacency bonuses to districts).
