+
+### Synopsis
+
+Downloads a LoopBack example project from our
+[GitHub monorepo](https://github.com/strongloop/loopback-next).
+
+
+```text
+lb4 example [options] [<example-name>]
+```
+
+### Options
+
+{% include_relative includes/CLI-std-options.md %}
+
+### Arguments
+
+`example-name` - Optional name of the example to clone. If provided, the tool
+will skip the example-name prompt and run in a non-interactive mode.
+
+See [Examples and tutorials](Examples-and-tutorials.html) for the list of
+available examples.
+
+### Interactive Prompts
+
+The tool will prompt you for:
+
+- Name of the example to download. If the name had been supplied from the
+command-line, the prompt is skipped.
+
+### Output
+
+The example project is downloaded to a new directory. For example, when
+downloading `getting-started` example, the tool stores the files
+under the newly created `loopback4-example-getting-started` directory.
