 The Azure Functions runtime supports [Java SE 8 LTS (zulu8.31.0.2-jre8.0.181-win_x64)](https://repos.azul.com/azure-only/zulu/packages/zulu-8/8u181/). This guide contains information about the intricacies of writing Azure Functions with Java.
 
-A Java function is a `public` method, decorated with the annotation `@FunctionName`. This method defines the entry for a Java function, and must be unique in a particular package. 
+As it happens to other languages, a Function App may have one or more functions. A Java function is a `public` method, decorated with the annotation `@FunctionName`. This method defines the entry for a Java function, and must be unique in a particular package. One Function App written in Java may have multiple classes with multiple public methods annotated with `@FunctionName`.
 
 This article assumes that you have already read the [Azure Functions developer reference](functions-reference.md). You should also complete the Functions quickstart to create your first function, by using [Visual Studio Code](functions-create-first-function-vs-code.md) or [Maven](functions-create-first-java-maven.md).
 
 ## Programming model 
 
 The concepts of [triggers and bindings](functions-triggers-bindings.md) are fundamental to Azure Functions. Triggers start the execution of your code. Bindings give you a way to pass data to and return data from a function, without having to write custom data access code.
 
+## Project Scaffolding
+
+The simplest way to scaffold a Java-based Azure Function project is to use `Apache Maven` archetypes. You can also find project generation wizards on Visual Studio Code, and the Azure Toolkits for Eclipse and IntelliJ.
+
+There are currently two Azure Functions archetypes for Maven:
+
+### Java Archetype
+
+This archetype is published under the following groupId and artifactId [com.microsoft.azure:azure-functions-archetype](https://search.maven.org/artifact/com.microsoft.azure/azure-functions-archetype/).
+
+```
+mvn archetype:generate \
+    -DarchetypeGroupId=com.microsoft.azure \
+	-DarchetypeArtifactId=azure-functions-archetype 
+```
+
+### Kotlin Archetype (Preview)
+
+This archetype is published under the following groupId and artifactId [com.microsoft.azure:azure-functions-kotlin-archetype](https://search.maven.org/artifact/com.microsoft.azure/azure-functions-kotlin-archetype/).
+
+```
+mvn archetype:generate \
+    -DarchetypeGroupId=com.microsoft.azure \
+	-DarchetypeArtifactId=azure-functions-kotlin-archetype
+```
+
+The source code of these archetypes can be found on the [Azure Maven Archetypes GitHub repository](https://github.com/microsoft/azure-maven-archetypes).

 You can use a shared [host.json](functions-host-json.md) file to configure the function app. Each function has its own code file (.java) and binding configuration file (function.json).
 
 You can put more than one function in a project. Avoid putting your functions into separate jars. The `FunctionApp` in the target directory is what gets deployed to your function app in Azure.
