# In addition to displaying the welcome page, this module

# Requirements checking. These are general, generic, things
# that are checked. They may not match with the actual requirements
# imposed by other modules in the system.
requirements:
    # Amount of available disk, in GiB. Floating-point is allowed here.
    # Note that this does not account for *usable* disk, so it is possible
    # to pass this requirement, yet have no space to install to.
    requiredStorage:    5.5

    # Amount of available RAM, in GiB. Floating-point is allowed here.
    requiredRam:        1.0

    # To check for internet connectivity, Calamares does a HTTP GET
    # on this URL; on success (e.g. HTTP code 200) internet is OK.
    internetCheckUrl:   http://google.com

    # List conditions to check. Each listed condition will be
    # probed in some way, and yields true or false according to
    # the host system satisfying the condition.
    #
    # This sample file lists all the conditions that are known.
    check:
        - storage
        - ram
        - power
        - internet
        - root
        - screen
    # List conditions that **must** be satisfied (from the list
    # of conditions, above) for installation to proceed.
    # If any of these conditions are not met, the user cannot
    # continue past the welcome page.
    required:
        # - storage
        - ram
        # - root

# GeoIP checking
#
# This can be used to pre-select a language based on the country
# the user is currently in. It *assumes* that there's internet
# connectivity, though. Configuration is like in the locale module,
# but remember to use a URL that returns full data **and** to
# use a selector that will pick the country, not the timezone.
#
# To disable, either comment-out the entire section, or set
# the *style* key to an unsupported format (e.g. `none`, as is
# done here).

geoip:
    style:  "none"
    url:    "https://geoip.kde.org/v1/ubiquity"  # extended XML format
    selector: "CountryCode"  # blank uses default, which is wrong

# User interface
#
# The "select language" icon is an international standard, but it
# might not theme very well with your desktop environment.
# Fill in an icon name (following FreeDesktop standards) to
# use that named icon instead of the usual one.
#
# Leave blank or unset to use the international standard.
#
# Known icons in this space are "set-language" and "config-language".
#
# languageIcon: set-language
