How do I rebrand OpenMRS

You need to do the following:

Using the Manage Apps function, add a new App Definition like:

{
  "id": "overrideSettings",
  "extensions": [
     {
        "id": "override.configureStandardHeader",
        "extensionPointId": "org.openmrs.module.appui.header.config",
        "type": "config",
        "extensionParams": {
            "logo-icon-url": "/url/path/to/the/image.png"
        }
    }
  ]
}

A prior version of this used to be documented on this page https://wiki.openmrs.org/pages/viewpage.action?pageId=93359429 but apparently it was overwritten.

@nirajkrsinghit, once you have gotten this working, could you collaborate with @ssmusoke to document this on this wiki page?
