 # Kommand
 
-A description will be provided.
+Kommand is a lightweight, declarative command framework written in Kotlin. You can declare command models vie annotations.
+The commands will be executed through reflections.
+
+## Example
+
+Here is an example of a command model.
+```kotlin
+package de.tammo.kommand.test
+
+import de.tammo.kommand.annotation.Model
+import de.tammo.kommand.annotation.Parameter
+import de.tammo.kommand.annotation.Parameters
+import de.tammo.kommand.annotation.Route
+
+@Model("test", ["alias"], [SubTestCommand::class])
+class TestCommand {
+
+    @Route(description = "Default route of the test command")
+    fun default() = true
+
+    @Route("parameter", "Route with parameters")
+    @Parameters([
+        Parameter("test", String::class),
+        Parameter("optional", String::class, optional = true)
+    ])
+    fun parameter(test: String, optional: String?) = true
+
+}
+```
+
+And this is how you register and execute them:
+```kotlin
+package de.tammo.kommand.test.executor
+
+import de.tammo.kommand.executor.CommandExecutor
+import org.junit.jupiter.api.Assertions.*
+import org.junit.jupiter.api.BeforeAll
+import org.junit.jupiter.api.Test
+import org.junit.jupiter.api.TestInstance
+
+class CommandExecutorTest {
+
+    fun composeCommand() = CommandExecutor.INSTANCE.register(listOf(TestCommand::class.java))
+
+    fun execute() = CommandExecutor.INSTANCE.execute("test")
+
+}
+```
+
+Look in the unit tests to see more examples.
+
+## Build with Gradle
+
+You have to add the `jitpack` repository:
+
+```groovy
+repository {
+    maven {
+        url 'https://jitpack.io' 
+    }
+}
+```
+
+Add the dependency:
+
+```groovy
+dependencies {
+    implementation("com.github.Tammo0987:Kommand:Version")
+}
+```
