+# Kotlin interpreter for Apache Zeppelin
+
+<div id="toc"></div>
+
+## Overview
+Kotlin is a cross-platform, statically typed, general-purpose programming language with type inference.
+It is designed to interoperate fully with Java, and the JVM version of its standard library depends on the Java Class Library, but type inference allows its syntax to be more concise.
+
+## Configuration
+<table class="table-configuration">
+  <tr>
+    <th>Name</th>
+    <th>Default</th>
+    <th>Description</th>
+  </tr>
+  <tr>
+    <td>zeppelin.kotlin.maxResult</td>
+    <td>1000</td>
+    <td>Max n
+  <tr>
+    <td>zeppelin.kotlin.shortenTypes</td>
+    <td>true</td>
+    <td>Display shortened types instead of full, e.g. Int vs kotlin.Int</td>
+  </tr>
+</table>
+
+## Using the Kotlin Interpreter
+In a paragraph, use %kotlin to select the Kotlin interpreter and then write your script.
+
+## Example
+
+```kotlin
+%kotlin 
+
+fun square(n: Int): Int = n * n
+```
+
+## Kotlin Context
+Kotlin context is accessible via `kc` object bound to the interpreter. 
 
 Review comment:
   Is this kotlin context specific for zeppelin or it is some kind of concept in kotlin ?
