- Downloaded version 0.3.5. from the wiki and extracted this to the modules folder
- Installed the module via the installation link on the modules section
- Put the specific code [ {cms_module module="userid"} ] on a newly created page with the name: login
- Navigate to the newly created for on the website
- Filled in the userid/password and clicked the button 'sign in'
