+# Instances section. This section is optional, and it defines custom instances for
+# modules of any kind. An instance entry has an instance name, a module name, and
+# a configuration file name.
+# The primary goal of this mechanism is to allow loading multiple instances of the
+# same module, with different configuration. If you don't need this, the instances
+# section can safely be left empty.
+# Module name plus instance name makes an instance key, e.g. "webview@owncloud",
+# where "webview" is the module name (for the webview viewmodule) and "owncloud"
+# is the instance name, which loads a configuration file named "owncloud.conf" from
+# any of the configuration file paths, including the webview module directory.
+# This instance key can then be referenced in the sequence section.
+# For all modules without a custom instance specification, a default instance is
+# generated automatically by Calamares. Therefore a statement such as "webview" in
+# the sequence section automatically implies an instance key of "webview@webview"
+# even without explicitly defining this instance, and the configuration file for
+# this default instance "<modulename>@<modulename>" is always assumed to be
+# "<modulename>.conf".
+# For more information on running module instances, run Calamares in debug mode
+# and check the Modules page in the Debug information interface.

+# Sequence section. This section describes the sequence of modules, both
+# viewmodules and jobmodules, as they should appear and/or run.
+# A jobmodule instance key (or name) can only appear in an exec phase, whereas
+# a viewmodule instance key (or name) can appear in both exec and show phases.
+# There is no limit to the number of show or exec phases. However, the same module
+# instance key should not appear more than once per phase, and deployers should
+# take notice that the global storage structure is persistent throughout the
+# application lifetime, possibly influencing behavior across phases.
+# A show phase defines a sequence of viewmodules (and therefore pages). These
+# viewmodules can offer up jobs for the execution queue.
+# An exec phase displays a progress page (with brandable slideshow). This progress
+# page iterates over the modules listed in the *immediately preceding* show phase,
+# and enqueues their jobs, as well as any other jobs from jobmodules, in the order
+# defined in the current exec phase.
+# It then executes the job queue and clears it. If a viewmodule offers up a job
+# for execution, but the module name (or instance key) isn't listed in the
+# immediately following exec phase, this job will not be executed.
+# WARNING: when upgrading from Calamares 1.1, this section requires manual
+# intervention. There are no fixed prepare/install/postinstall phases any more,
+# and all limitations on the number of phases, number of pages, and number of
+# instances are lifted.
