+### stashcontrol.lua
+
+This module handles logic for interacting with stashes—shared inventories for crafting, jobs, or storage systems.
+
+- **checkStashItem(stashes, itemTable)**
+
+  - Retrieves (or updates) a local stash cache entry with a timeout.
+  - **Example:**
+    ```lua
+    local found, foundinStash = checkStashItem({"crafting_stash"}, { item = "steel", amount = 2 })
+    if found then print("Found item in "..foundInStash) end
+    ```
+
+- **openStash(data)**
+
+  - Opens a stash using the active inventory system.
+  - Checks for job or gang restrictions before opening the stash.
+  - **Example:**
+    ```lua
+    openStash({
+        stash = "playerStash",
+        label = "Player Stash",
+        coords = vector3(100, 200, 30)
+    })
+    ```
+
+- **getStash(stashName)**
+
+  - Retrieves the stash data by name (usually used for querying contents).
+  - **Example:**
+    ```lua
+    local items = getStash("playerStash")
+    for k, v in pairs(items) do
+        print(k)
+    end
+    ```
+
+- **stashRemoveItem(stashItems, stashName, items)**
+
+  - Removes specified items from a stash. Used during crafting or transfers.
+  - **Example:**
+    ```lua
+    stashRemoveItem(currentItems, "playerStash", { iron = 2, wood = 5 })
+    ```
