Love your mod, and thought I'd offer a few edits on the wiki/Curseforge entry. Feel free to accept or ignore as many of my edits as you like.

This mod gives you the feeling of being a man from the stone age. No more magically created planks from wood logs; the way to your first crafting table is long and dangerous. In prehistoric ages, animals were not domesticated, and the same applies to this mod. There are no cows, sheeps, pigs, or chickens. Instead you'll find their ancestors (aurochs, mouflons, boars, and fowls), all of whom are quit upset when you attack them or their friends.

New blocks
Flint workbench - Allows you to craft primitive tools & another useful things. To craft an item from the workbench, right-click it with a flint knife.
Drying rack - Necessary for drying grass.
Tanning rack - Used for tanning raw hide. Right-click raw hide with a flint knife multiple times until leather is produced. Then right-click with empty hand to remove the leather.
Stone chest - Doesn't have much space, but still useful.
Tree stump - If you want planks, you must chop your logs first!
Aqueduct - Allows you to transfer water nearer to your crops. To activate watering with the aqueduct, right-click it with an empty hand. You should then see bubbles if it is activated and has water. Activated aqueducts also randomly apply a bone meal effect to nearby crops and grass.
Dried grass bed - Not as soft as a wool bed, but you can still sleep there.
Feeder - If you want your animals to grow faster, you definitely need this.
Millstone - Necessary if you want to mill your wheat to flour or sugar canes to sugar. Shift-right-click with an empty hand to insert or remove items, then right-click to activate the mill. Your item will be milled after four rotations.

Other useful things
You can make fire by dropping dried grass the on ground and right-clicking with a stick in your left and right hand.
Wild animals can be bred to their domesticated (vanilla) forms after three generations. The generation of the child is calculated as the minimum of the two parents' age plus one. Thus, do not breed children with parents, as their generation will stay the same.

Planks - Can be made by chopping logs on a tree stump with an axe.
Wooden items can only be harvested with an axe.

I tried to keep the formatting consistent throughout and to not change too much of your wording, but to clarify where necessary and fix grammar/spelling. Hope this is helpful, and thanks again for a great mod!

Thank you, I updated wiki with your fixes 👍
