+# Multiple value assignment to attributes
+
+This package supports the multiple assignment of attribute values. This allows you to describe your articles in more detail and offer more flexible filters.
+
+Instead of 
+* Colour: yellow
+* Material: cotton
+
+you can now maintain further details:
+* Color: yellow
+* Colour: black
+* Material: cotton
+* Material: Polyester
+
+These additional filter options can be used in our [advanced search](https://packagist.org/packages/d3/extsearch) module, for example.
+
+## Install
+
+Run this composer statement in your shop. Adjust this command if your installation requires it.
+
+```
+composer require d3/d3/attributemultivalues --update-no-dev
