+  @mixins [DemoMixin1, DemoMixin2]
+
+Add one or more ReactiveModels as mixin to the app. The mixins need to be passed as a Vector.
+This feature is meant to be able to design functionalities that can be reused within other apps.
+
+All fields, client data, and js functions like watchers, life cycle hooks, etc are automatically embedded.
+
+However, the recommended way of embedding the fields
+is via the `@mixin` in the app definition, because only then they are automatically synchronised according to their definition.
+So in order to include a mixin with data and functions, two steps are needed.
+
+This feature is still tentative and might be redesigned in the future.
+```julia
+@app GreetMixin begin
+  @in name = "John Doe"
+end
+
+@mounted GreetMixin = "console.log('Just mounted the App including the GreetMixin')"
+
+@methods GreetMixin \"\"\"
+greet: function() { console.log('Hi ' + this.name + '!') }
+\"\"\"
+
+@mixins [GreetMixin]
+
+@app begin
+  @mixin GreetMixin
+  @in s = "Hi"
+  @in i = 10
