To create Gliimly application with default settings use an option of gg utility:
gg -k my-app
where "my-app" is your application name. If you already have an application with that name, nothing is done, so this is an idempotent operation.
If you already have source code, you can create and compile your application in one step:
gg -k my-app -q
which is a neat shortcut.
What's default settings? Well, it means your application directory (in "/var/lib/gg/my-app") will be owned by the currently logged on user (and other users can't access it), and any Unix socket can connect to your application server. This is a typical setup you'd probably use in most cases, so it's a useful one.
If you'd like to have more options in creating a Gliimly application, see service manager).
