+FoodsoftMessages
+================
+
+This plugin adds messages to foodsoft. A new 'Messages' 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_messages', path: 'lib/foodsoft_messages'
+```
+
+This plugin introduces the foodcoop config option `use_messages`, which can be
+set to `false` to disable messages. 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).

+FoodsoftWiki
+============
+
+This plugin adds wiki pages to foodsoft. A new 'Wiki' menu is added next to
+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
+# we use the git version of acts_as_versioned, so this needs to be in foodsoft's Gemfile
+gem 'acts_as_versioned', git: 'git://github.com/technoweenie/acts_as_versioned.git'
+gem 'foodsoft_wiki', path: 'lib/foodsoft_wiki'
+```
+
+This plugin introduces the foodcoop config option `use_wiki`, which can be set
+to `false` to disable the wiki. 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).
