How do I Get and Set Module data using datastore?

I've decided to make a murder-mystery related game, but I don't know how to get anywhere with the module I have made.

I was planning to use folders and just use bool values, but that would take too much of my time. Modules are much cleaner/neater to use and find any data you want in my opinion.

Overall, I just need help with the modules and how can I get/set the data inside of it using :GetAsync() and SetAsync()? So that once that player joins the starter table inserts a GUI with a basic knife image, rarity, imageID, textureID, MeshID.

What I can do so far:

  • Loop through a table to get the data's variable. Using for pairs().
  • Create a table inside of a table. (Obviously)

What I can't do so far:

 • Save the player's module data.
 • Create the knife using the table that has the meshID and textureID.

What I did:

 -- Module script:
local Knives = {ItemName = {"Rarity", "ImageID", "MeshID", "TextureID"}; ItemName2 = {"Rarity", "ImageID", "MeshID", "TextureID"};}

return Knives

-- script:
local M_Knives = require(script:FindFirstChild("M_Knives"))

for i, v in pairs(M_Knives) do
    print(v[1])
end
