How to Create a Portlet (Zenoss Ver.3)

I'm working with Zenoss 3.2.1, so I have downloaded "Zenoss_Developers_Guide_08-102010-3.0-v01.pdf" file. However, when I follow the instructions to "Create a Dashboard Portlet" apparently the version is not same, because it mentions a folder ReportListPortletPack and a file ReportListPortlet.js that are not in my ZenPack directory. Who has the correct instructions for this Zenoss Version (v3)

Manually, I have created the file and folder, but when I tried to install using "zenpack --install ReportListPortletPack" I got an error:
