+The enchantments can be added to Shulker Boxes and optionally to Ender Chests (see [configuration](#configuration)) on an anvil.
 
 ### Siphon
 With the Siphon enchantment, any item that you pick up will be immediately stored in an enchanted container as long as that container already has a non-full stack of that exact item inside.

 Players without the mod on their client cannot see these enchantments on enchanted books and enchanted containers.
 
 ## Configuration
-*coming soon...*
+A few aspects of the mod can be configured in the `config/enchanted_shulkers.toml` config file. On first launch a default file is generated. Below is a list of available options.
+
+| **Option**                 | **Possible Values** | **Default Value** | **Description**                                             |
+|----------------------------|---------------------|-------------------|-------------------------------------------------------------|
+| `refill_offhand`           | `true`, `false`     | `true`            | Allow refilling stacks in the offhand                       |
+| `refill_non_stackables`    | `true`, `false`     | `false`           | Allow refilling non-stackable items like Totems of Undying  |
+| `enchantable_ender_chest`  | `true`, `false`     | `false`           | Allows Ender Chests to also be enchanted                    |
+| `colorize_container_names` | `true`, `false`     | `false`           | Show the names of placed enchanted containers in aqua color |

+## For Mod Developers
+If your Mod adds a new container that should support these enchantments, you must simply add the container to the `enchanted_shulkers:portable_container` item tag.
+To do that, create the file `portable_container.json` inside the `src/main/resources/data/enchanted_shulkers/tags/items/` folder of your mod with following contents:
+
+```json
+{
+  "replace": false,
+  "values": [
+    "your_mod_namespace:your_container_item"
+  ]
+}
+```
+
+If your container does not extend the vanilla Shulker Box class, you might have to manually implement the [`EnchantableBlockEntity`](https://github.com/RubixDev/EnchantedShulkers/blob/1.19/src/main/java/de/rubixdev/enchanted_shulkers/EnchantableBlockEntity.java) interface and support rendering the enchantment glint and display name colorizer.
