+# Eclipse Ditto™ - WoT (Web of Things) Tooling :: WoT Kotlin Generator
+
+A tool for generating type-safe Kotlin data classes and DSLs from Web of Things (WoT) Thing models with path 
+generation capabilities for Eclipse Ditto.
+
+**Project URL:** https://github.com/eclipse-ditto/ditto-wot-tooling
+
+## Overview
+
+The WoT Kotlin Generator transforms WoT Thing Models (JSON-LD format) into strongly-typed Kotlin classes, providing:
+
+- **Type Safety**: Compile-time validation of WoT schema constraints
+- **DSL Support**: Fluent builder patterns for easy object construction
+- **Eclipse Ditto Integration**: Built on top of the Eclipse Ditto WoT API and Model
+- **Path Generation**: Type-safe path construction for RQL queries
+- **Flexible Configuration**: Multiple strategies for enum generation and class naming
+- **Suspend Function Support**: Optional coroutine support for asynchronous DSL operations
+
+## Module Structure
+
+This is a multi-module Maven project consisting of:
+
+### 1. wot-kotlin-generator-common-models
+Common model classes and base interfaces used by generated code:
+- Path generation APIs
+- DSL base classes
+- Serialization/deserialization utilities
+- Feature and property interfaces
+
+**Consumers must include this module as a dependency** to use the generated code.
+
+```xml
+<dependency>
+    <groupId>org.eclipse.ditto</groupId>
+    <artifactId>wot-kotlin-generator-common-models</artifactId>
+    <version>0-SNAPSHOT</version>
+</dependency>
+```
+
+### 2. wot-kotlin-generator-maven-plugin
+Maven plugin for code generation:
+- WoT Thing Model parsing
+- Kotlin code generation
+- Enum generation strategies
+- Class naming strategies
+- DSL generation
+
+**Add this plugin to your build** to generate Kotlin code from WoT Thing Models.
+
+```xml
+<plugin>
+    <groupId>org.eclipse.ditto</groupId>
+    <artifactId>wot-kotlin-generator-maven-plugin</artifactId>
+    <version>0-SNAPSHOT</version>
+    <executions>
+        <execution>
+            <goals>
+                <goal>codegen</goal>
+            </goals>
+        </execution>
+    </executions>
+</plugin>
+```
+
+## Quick Start
+
+See the [plugin README](wot-kotlin-generator-maven-plugin/README.md) for detailed usage instructions, configuration options, and examples.
+
+### Basic Usage
+
+1. Add both the common-models dependency and the plugin to your `pom.xml`
+2. Configure the plugin with your WoT Thing Model URL
+3. Run: `mvn clean compile`
+4. Use the generated Kotlin classes in your code
+
+## Building from Source
+
+```bash
+cd wot-kotlin-generator
+mvn clean install
+```
+
+This will build both modules:
+1. `wot-kotlin-generator-common-models` (built first as a dependency)
+2. `wot-kotlin-generator-maven-plugin`
+
+## Prerequisites
+
+- Java 21 or later
+- Maven 3.9+ or Maven Wrapper
+- Kotlin 2.0+ (for consuming projects)
+
+## Technology Stack
+
+- **Kotlin**: 2.2.10
+- **Eclipse Ditto**: 3.8.2
+- **KotlinPoet**: 2.2.0 (for code generation)
+- **Jackson**: 2.19.2 (for JSON processing)
+- **Ktor**: 3.2.0 (for HTTP client)
+- **Maven Plugin API**: 3.9.11
+
+## Key Features
+
+### Type-Safe Path Generation
+Generate compile-time validated paths for Eclipse Ditto queries:
+
+```kotlin
+val path = pathBuilder().from(start = Thing::features)
+    .add(Features::thermostat)
+    .add(Thermostat::properties)
+    .add(ThermostatProperties::temperature)
+    .buildSearchProperty()
+    .gt(20.0)
+```
+
+### Flexible Enum Generation
+Choose between inline enums or separate class enums based on your needs.
+
+### Multiple Naming Strategies
+Configure how generated classes are named to match your project conventions.
+
+### Suspend DSL Support
+Generate coroutine-friendly DSL functions for asynchronous operations.
