 A plugin for Controls-kt device server on top of modbus-rtu/modbus-tcp protocols
 
+## Features
+
+ - [modbusRegistryMap](src/main/kotlin/space/kscience/controls/modbus/ModbusRegistryMap.kt) : Type-safe modbus registry map. Allows to define both single-register and multi-register entries (using DataForge IO). 
+Automatically checks consistency.
+ - [modbusProcessImage](src/main/kotlin/space/kscience/controls/modbus/DeviceProcessImage.kt) : Binding of slave (server) modbus device to Controls-kt device
+ - [modbusDevice](src/main/kotlin/space/kscience/controls/modbus/ModbusDevice.kt) : A device with additional methods to work with modbus registers.
+
+
+## Usage
+
+## Artifact:
+
+The Maven coordinates of this project are `space.kscience:controls-modbus:0.2.0`.
+
+**Gradle Kotlin DSL:**
+```kotlin
+repositories {
+    maven("https://repo.kotlin.link")
+    //uncomment to access development builds
+    //maven("https://maven.pkg.jetbrains.space/spc/p/sci/dev")
+    mavenCentral()
+}
