=== Create the directory structure

In a project directory of your choosing, create the following
subdirectory structure:

[subs="attributes"]
```
├── {yarn_base_appmain}
│   └── src
│       └── main
│           ├── resources
│           └── java
│               └── hello
│                   └── appmain
├── {yarn_base_container}
│   └── src
│       └── main
│           ├── resources
│           └── java
│               └── hello
│                   └── container
├── {yarn_base_client}
│   └── src
│       └── main
│           ├── resources
│           └── java
│               └── hello
│                   └── client
└── {yarn_base_dist}
```

for example, on *nix systems, with:

[subs="attributes"]
```
mkdir -p {yarn_base_appmain}/src/main/resources
mkdir -p {yarn_base_appmain}/src/main/java/hello/appmain
mkdir -p {yarn_base_container}/src/main/resources
mkdir -p {yarn_base_container}/src/main/java/hello/container
mkdir -p {yarn_base_client}/src/main/resources
mkdir -p {yarn_base_client}/src/main/java/hello/client
mkdir -p {yarn_base_dist}
```
