Installation Instructions?

[amin-sagar]

Hello.
Are there any updated installation instructions?
It seems gradle.properties doesn't exist anymore.
I tried setting the jdk path in build.gradle.kts

 jpackage {

                jpackageHome = System.getProperty("/home/amin/Downloads/jdk-14.0.2")
                        ?: throw NoSuchElementException("""
                                |add a systemProp.jpackage.home = /path/to/jdk14 to gradle.properties.
                                |Requires JDK 14 or higher to be installed.
                        """.trimMargin())
                imageName = "Osprey"
                installerName = imageName

But, I don't understand how to proceed after this.
Also, do I need to download molscope and set the following paths in settings.gradle.kts file?

includeBuild(System.getProperty("molscope.path"))
includeBuild(System.getProperty("osprey.path"))
includeBuild(System.getProperty("ospreyservice.path"))

I would be really grateful for any suggestions.
Amin.
