Steps:

1. Add workflow configuration:

• create app/config/workflows.yml and paste (for v3: config/packages/ezplatform_workflow.yaml)

      
  ezpublish:
      system:
          default:
          #admin:
              workflows:
                  lp_workflow:
                      name: 'Landing Page Workflow'
                      matchers:
                          content_type: landing_page
                      stages:
                          draft:
                              label: 'Draft'
                              color: '#aaa'
                          design:
                              label: 'Design'
                              color: '#9ff'
                          proofread:
                              label: 'Proofread'
                              color: '#99f'
                          done:
                              color: '#0f0'
                              last_stage: true
                      initial_stage: draft
                      transitions:
                          to_design:
                              from: draft
                              to: design
                              icon: '/bundles/ezplatformadminui/img/ez-icons.svg#approved'
                              label: 'Send to Design'
                              notification:
                                  user_group: 13 # Notify "Editors" group
                                  user: 14 # ... and "Administrator" user
                          to_proofread:
                              from: design
                              to: proofread
                              icon: '/bundles/ezplatformadminui/img/ez-icons.svg#approved'
                              label: 'Send to Proofread'
                              notification:
                                  user_group: 13 # Notify "Editors" group...
                                  user: 14 # ... and "Administrator" user
                          to_done:
                              from: proofread
                              to: done
                              icon: '/bundles/ezplatformadminui/img/ez-icons.svg#approved'
                              label: 'Done'
  

• import in app/config/config.yml (for v3: tere is no need to do this step)

     - { resource: workflows.yml } 

2. Log in
3. Go to Page/site
4. Click and select Landing Page
