+
+#### Namespace and Group Name
+Here you can create your own custom naming for the reference loader.
+
+The custom naming is split into two parts: namespace and group name. If you don't set the namespace or the group name, an error will occur.
+Here's the different variables you can use:
+
+<div class="row markdown">
+<div class="col col--5 markdown">
+
+| Token | Description |
+|---|---|
+|`{asset_name}` | Asset name |
+|`{asset_type}` | Asset type |
+|`{subset}` | Subset name |
+|`{family}` | Subset family |
+
+</div>
+</div>
+
+The namespace field can contain a single group of '#' number tokens to indicate where the namespace's unique index should go. The amount of tokens defines the zero padding of the number, e.g ### turns into 001.
+
+Warning: Note that a namespace will always be prefixed with a _ if it starts with a digit.
