+
+A small and simple `.proto` file generator. Generates a protobuf schema from the given kotlin classes.
+
+### Usage
+
+```xml
+
+<dependency>
+    <groupId>io.github.smyrgeorge</groupId>
+    <artifactId>protogen4k</artifactId>
+    <version>x.y.z</version>
+</dependency>
+```
+
+or using gradle:
+
+```kotlin
+implementation("io.github.smyrgeorge:protogen4k:x.y.z")
+```
+
+### Examples
+
+Let's see an example.
+
+```kotlin
+package io.github.smyrgeorge.datasuite.converter.protobuf.examples
+
+import io.github.smyrgeorge.datasuite.converter.protobuf.KotlinClassToProtobuf
+import io.github.smyrgeorge.datasuite.converter.protobuf.annotation.ProtoFile
+
+class Main
+
+@ProtoFile(name = "a_class.proto", schema = "schema1")
+data class AClass(
+    val a: String,
+    val b: List<AnEnum>
+) {
+    enum class AnEnum {
+        A, B
+    }
+}
+
+fun main(args: Array<String>) {
+    KotlinClassToProtobuf.generate(
+        topicPrefix = "sample",
+        workDirectory = "examples/src/main/proto",
+        classes = listOf(AClass::class),
+        protoPackage = "io.github.smyrgeorge.datasuite.proto"
+    )
+}
+```
+
+The above `kotlin` code will generate 2 `.proto` files.
+
+```protobuf
+// file: a_class.proto
+syntax = "proto3";
+
+package io.github.smyrgeorge.datasuite.proto;
+
+option java_package = "io.github.smyrgeorge.datasuite.proto";
+option java_outer_classname = "AClassProto";
+
+import "default.proto";
+
+message AClass {
+  string a = 1;
+  repeated AClassAnEnum.Enum b = 2;
+}
+```
+
+```protobuf
+// file: default.proto
+syntax = "proto3";
+
+package io.github.smyrgeorge.datasuite.proto;
+
+option java_package = "io.github.smyrgeorge.datasuite.proto";
+option java_outer_classname = "DefaultProto";
+
+message AClassAnEnum {
+  enum Enum {
+    PROTO_EMPTY = 0;
+    A = 1;
+    B = 2;
+  }
+}
+```
