+FoodsoftDocuments
+=================
+
+This plugin adds documents to foodsoft. A new 'Documents' menu entry is added below the 'Foodcoops' menu in the navigation bar.
+
+This plugin is enabled by default in foodsoft, so you don't need to do anything
+to install it. If you still want to, for example when it has been disabled,
+add the following to foodsoft's Gemfile:
+
+```Gemfile
+gem 'foodsoft_documents', path: 'lib/foodsoft_documents'
+```
+
+This plugin introduces the foodcoop config option `use_documents`, which can be
+set to `true` to enable documents. May be useful in multicoop deployments.
+
+This plugin is part of the foodsoft package and uses the GPL-3 license (see
+foodsoft's LICENSE for the full license text).
