+
+`contents.json` is a file that is _probably_ used for the game to process the pack files more easily. It is _probably_ intended for marketplace content creators and Mojang, it is not required to have this file in the pack for the pack to work properly.
+
+You will find there some instructions about the usage of this file.
+
+## Structure of the file
+
+`contents.json` is located at the root of the add-on directory. It contains a list of the files that are included in the pack.
+Example:
+
+<CodeHeader>RP/contents.json</CodeHeader>
+
+```json
+{
+	"content": [
+		{
+			"path": "texts/en_US.lang"
+		},
+		{
+			"path": "contents.json"
+		},
+		{
+			"path": "manifest.json"
+		},
+		{
+			"path": "animations/my_animation.animation.json"
+		},
+		{
+			"path": "animation_controllers/my_ac.ac.json"
+		},
+		{
+			"path": "entity/my_entity.entity.json"
+		},
+		{
+			"path": "textures/textures_list.json"
+		},
+		{
+			"path": "textures/blocks/my_block.png"
+		}
+	]
+}
+```
+
+<FolderView
+	:paths="[
+    'RP/texts/en_US.lang',
+    'RP/manifest.json',
+    'RP/contents.json',
+    'RP/animations/my_animation.animation.json',
+    'RP/animation_controllers/my_ac.ac.json',
+    'RP/entity/my_entity.entity.json',
+    'RP/textures/texture_list.json',
+    'RP/textures/blocks/my_block.png'
+]"
+> </FolderView>
+
+## Automatizing the process
+
+The `contents.json` file can be generated automatically by the game itself, it is very recommended to decrease the risks of making mistakes. However, the file must be prepared first. Create a new empty file called `contents.json` in the root directory of your add-on, and add empty brackets.
+
+<CodeHeader>BP|RP/contents.json</CodeHeader>
+
+```json
+{}
+```
+
+The file content will be automatically written next time the game is launched.
+
+## Additional information
+
+-   The automatic process can be achieved no matter what is the location of the pack (Development folders or normal folders).
+-   Do not make multiple `contents.json` for subpacks, the file at the root of the pack is sufficient.
+-   This file is not required for the addon to work properly.
