+# KAU :fastadapter
+
+Collection of kotlin bindings and custom IItems for [Fast Adapter](https://github.com/mikepenz/FastAdapter)
+
+## KauIItems
+
+Abstract base that extends `AbstractIItems` and contains the arguments `(layoutRes, ViewHolder lambda, idRes)` in that order. 
+Those variables are used to override the default abstract functions.
+If a layout is only used for one item, it may also be used as the id, which you may leave blank in this case.
+The ViewHolder lambda is typically of the form `::ViewHolder`
+Where you will have a nested class `ViewHolder(v: View) : RecyclerView.ViewHolder(v)`
+
+## IItem Templates
+
+* CardIItem - generic all encompassing card item with a title, description, imageview, and button. 
+All items except for the title are optional.
+* HeaderIItem - simple title container with a big top margin
