+REST API for compiling and executing Kotlin code.
+Server provides the API for [Kotlin Playground](https://github.com/JetBrains/kotlin-playground) library.
+
+## How to start
+
+Download Kotlin dependencies and build an executor before starting the server:
+
+```shell script
+$ ./gradlew build -x test 
+```
+
+Start the Spring Boot project.
+
+## API Documentation
+
+**Run code JVM**
+
+```shell script
+curl -X POST \
+  http://localhost:8080/api/compiler/run \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "args": "1 2 3",
+    "files": [
+        {
+            "name": "File.kt",
+            "text": "fun main(args: Array<String>) {\n    println(\"123\")\n}"
+        }
+    ]
+}'
+```
+
+**Translate Kotlin code to JavaScript code**
+
+```shell script
+curl -X POST \

+      "text": "fun start(): String = \"OK\""
+    },
+    {
+      "name": "test0.kt",
+      "text": "import org.junit.Assert\nimport org.junit.Test\n\nclass TestStart {\n    @Test fun testOk() {\n        Assert.assertEquals(\"OK\", start())\n    }\n}"
+    },
+    {
+      "name": "test1.kt",
+      "text": "package koans.util\n\nfun String.toMessage() = \"The function '\''$this'\'' is implemented incorrectly\"\n\nfun String.toMessageInEquals() = toMessage().inEquals()\n\nfun String.inEquals() = this"
+    }
+  ]
+}'
+```
+
+**Code completions**
+
+```shell script
+curl -X POST \
+  'http://localhost:8080/api/compiler/complete?line=1&ch=12' \

+  -d '{
+  "files": [
+    {
+      "name": "File.kt",
+      "text": "fun main() {\n    3.0.toIn\n}"
+    }
+  ]
+}'
+```
+

+      "text": "fun main() {\n    println(\"Hello, world!!!\")ass\n}"
+    }
+  ]
+}'
+```
+
+**Get the current Kotlin version**
+
+```shell script
+curl -X GET http://localhost:8080/api/compiler/version
+```
+
+
+Server also supports an [API](https://github.com/JetBrains/kotlin-playground) for the Kotlin Playground library. 
+
+## How to add your dependencies to kotlin compiler :books:
+
+Just put whatever you need as dependencies to [build.gradle.kts](https://github.com/AlexanderPrendota/kotlin-compiler-server/blob/master/build.gradle.kts) via a task called `kotlinDependency`:
+
+```
+ kotlinDependency "your dependency"
+```
+
+NOTE: If the library you're adding uses reflection, accesses the file system, or performs any other type of security-sensitive operations, don't forget to
+configure the [executors.policy](https://github.com/AlexanderPrednota/kotlin-compiler-server/blob/master/executors.policy). [Click here](https://docs.oracle.com/javase/7/docs/technotes/guides/security/PolicyFiles.html) for more information about *Java Security Policy*.
+
+**How to set Java Security Policy in `executors.policy`**
+
+If you want to configure a custom dependency, use the marker `@LIB_DIR@`:
+
+```
+grant codeBase "file:%%LIB_DIR%%/junit-4.12.jar"{
+  permission java.lang.reflect.ReflectPermission "suppressAccessChecks";
+  permission java.lang.RuntimePermission "setIO";
+  permission java.io.FilePermission "<<ALL FILES>>", "read";
+  permission java.lang.RuntimePermission "accessDeclaredMembers";
+};
+```
+
+## Kotlin release guide
+
+1) Update kotlin version in [gradle.properties](https://github.com/AlexanderPrendota/kotlin-compiler-server/blob/master/gradle.properties)
+2) Just make sure everything is going well via the task: 
+
+```shell script
+$ ./gradlew build
+```
