+Multipart upload example
+========================
+
+To try this example, you need GNU `make` and `git` in your PATH.
+
+To build the example, run the following command:
+
+``` bash
+$ make
+```
+
+To start the release in the foreground:
+
+``` bash
+$ ./_rel/bin/upload_example console
+```
+
+Then point your browser at [http://localhost:8080](http://localhost:8080).
+
+The uploaded file will be displayed in the shell directly.
