+
+Minecraft Bedrock allows us to add custom items into our world with various vanilla-like properties
+
+This tutorial will cover how to create basic items for the stable version of Minecraft.
+
+## Registering Items
+
+Item definitions are structured similarly to entities: they contain a description and a list of components that defines the item's behavior.
+
+Below is the **minimum** behavior-side code to get a custom item into the creative inventory.
+
+<CodeHeader>BP/items/custom_item.json</CodeHeader>
+
+```json
+{
+    "format_version": "1.20.50",
+    "minecraft:item": {
+        "description": {
+            "identifier": "wiki:custom_item",
+            "menu_category": {
+              "category": "construction"
+            }
+        },
+        "components": {} // Must be here, even if empty!
+    }
+}
+```
+
+### Item Description
+
+- Defines the item's identifier - a unique ID in the format of `namespace:identifier`.
+- Configures which `menu_category` the item is placed into.
+    - Also takes the optional parameters `group` and `is_hidden_in_commands`.
+
+## Adding Components
+
+Right now, our custom item is using the default component values (which can be found [here](/items/item-components)).
+
+Let's configure our own functionality!
+
+<CodeHeader>BP/items/custom_item.json</CodeHeader>
+
+```json
+{
+    "format_version": "1.20.50",
+    "minecraft:item": {
+        "description": {
+            "identifier": "wiki:custom_item",
+            "menu_category": {
+                "category": "construction"
+            }
+        },
+        "components": {
+            "minecraft:damage": {
+                "value": 10
+            },
+            "minecraft:durability":{
+                "max_durability": 36
+            },
+            "minecraft:hand_equipped": {
+                "value": true
+            }
+        }
+    }
+}
+```

+
+## Applying Textures
+
+We need to create a texture shortname to link it to an image in `RP/textures/item_texture.json`.
+
+<CodeHeader>RP/textures/item_texture.json</CodeHeader>
+
+```json
+{
+    "resource_pack_name": "wiki",
+    "texture_name": "atlas.items",
+    "texture_data": {
+        "custom_item": {
+            "textures": "textures/items/custom_item"
+        }
+    }
+}
+```
+
+In our item file, we will add the `minecraft:icon` component to apply the texture.
+
+<CodeHeader>BP/items/custom_item.json</CodeHeader>
+
+```json
+{
+    "format_version": "1.20.50",
+    "minecraft:item": {
+        "description": {
+            "identifier": "wiki:custom_item",
+            "menu_category": {
+                "category": "construction"
+            }
+        },
+        "components": {
+            "minecraft:icon": {
+                "texture": "custom_item"
+            }
+        }
+    }
+}
+```
+
+## Defining Names
+
+Finally, we will give our item a name. Additionally, you can use the [Display Name](/items/item-components#display_name) component.
+
+<CodeHeader>RP/texts/en_US.lang</CodeHeader>
+
+```c
+tile.wiki:custom_item.name=Custom Item
+```
