-/**
- * Provides the Vault Chat service through the use of normal permission nodes.
- *
- * Prefixes / Suffixes:
- * Normal inheritance rules apply.
- * Permission Nodes = prefix.priority.value OR suffix.priority.value
- * If a user/group has / inherits multiple prefixes and suffixes, the one with the highest priority is the one that
- * will apply.
- *
- * Meta:
- * Normal inheritance rules DO NOT apply.
- * Permission Nodes = meta.node.value
- *
- * Node that special characters used within LuckPerms are escaped:
- * See {@link me.lucko.luckperms.utils.ArgumentChecker#escapeCharacters(String)}
- *
- * Registered on normal priority so other plugins can override.

+# +------------------------------------------------------------------------+ #
+
+# This section allows you to define defaults to give users whenever they connect to the server.
+# The default assignments are highly configurable and conditional.
+#
+# There is one default assignment built into LuckPerms, which will add all users to the "default" group if they
+# are not a member of any other group. This setting cannot be disabled. However, you can use this section to add more of
+# your own.
+#
+# IMPORTANT:
+# In order to save storage space, LuckPerms does not store users who have no permissions defined, and are only a member
+# of the default group. Adding default assignments to this section will negate this effect. It is HIGHLY RECCOMENDED
+# that instead of assigning defaults here, you add permissions to the "default" group, or set the "default" group to inherit
+# other groups, and then use the group-name-rewrite rule above.
+#
+# It is also important to note that these rules are considered every time a player logs into the server, and are applied
+# directly to the user's data. Simply removing a rule here will not reserse the effect of that rule on any users who have
+# already had it applied to them.
+#
+# The "has" and "lacks" conditions below support standard boolean logic, using the 'and' & 'or' characters used in Java.
+# e.g. "(some.other.permission | some.permission.other) & some.thing.else" == a user has 'some.other.permission', or
+# 'some.permission.other', and they also have 'some.thing.else'
+#
+# Groups are represented by the permission node: group.<group name>
+# Per server and per world nodes are represented by: "server-world/permission" or "server/permission"
+#
+# Within conditions, permission nodes MUST be escaped using "<" and ">". See the example below.
+#
+# Explaination of the examples below: (they're just to demonstrate the features & use cases)
+#
+# rule1:
+# If a user is either in the vip or vip+ group, and they have the "titles.titlecollector" permission set to true, and the
+# "some.random.permission" set to false... if they're not in the group "prison_titlepack" on the "prison" server, then
+# give add them to the "prison_titlepack" group on the "prison" server, and remove "some.random.permission".
+#
+# rule2:
+# If the user isn't in any of the following groups on the skyblock server: sb_level1, sb_level2, sb_level3, then add
+# them to sb_level1 on the skyblock server.
+#
+# rule3:
+# If the user is a member of the default group, remove them from default, add them to member, and set their primary group
+# to member.
+#
+# WARNING: Unlike internal commands, this system does not ensure that a group exists before adding a user to it.
+# It also does not unsure that a user is a member of a group before making that group their primary group.
+#
+# Before you use "give: group.<name>" or "set-primary-group", make sure that the group exists, and that the user is
+# a member of the group.

+# +------------------------------------------------------------------------+ #
+
+# This section allows you to define defaults to give users whenever they connect to the server.
+# The default assignments are highly configurable and conditional.
+#
+# There is one default assignment built into LuckPerms, which will add all users to the "default" group if they
+# are not a member of any other group. This setting cannot be disabled. However, you can use this section to add more of
+# your own.
+#
+# IMPORTANT:
+# In order to save storage space, LuckPerms does not store users who have no permissions defined, and are only a member
+# of the default group. Adding default assignments to this section will negate this effect. It is HIGHLY RECCOMENDED
+# that instead of assigning defaults here, you add permissions to the "default" group, or set the "default" group to inherit
+# other groups, and then use the group-name-rewrite rule above.
+#
+# It is also important to note that these rules are considered every time a player logs into the server, and are applied
+# directly to the user's data. Simply removing a rule here will not reserse the effect of that rule on any users who have
+# already had it applied to them.
+#
+# The "has" and "lacks" conditions below support standard boolean logic, using the 'and' & 'or' characters used in Java.
+# e.g. "(some.other.permission | some.permission.other) & some.thing.else" == a user has 'some.other.permission', or
+# 'some.permission.other', and they also have 'some.thing.else'
+#
+# Groups are represented by the permission node: group.<group name>
+# Per server and per world nodes are represented by: "server-world/permission" or "server/permission"
+#
+# Within conditions, permission nodes MUST be escaped using "<" and ">". See the example below.
+#
+# Explaination of the examples below: (they're just to demonstrate the features & use cases)
+#
+# rule1:
+# If a user is either in the vip or vip+ group, and they have the "titles.titlecollector" permission set to true, and the
+# "some.random.permission" set to false... if they're not in the group "prison_titlepack" on the "prison" server, then
+# give add them to the "prison_titlepack" group on the "prison" server, and remove "some.random.permission".
+#
+# rule2:
+# If the user isn't in any of the following groups on the skyblock server: sb_level1, sb_level2, sb_level3, then add
+# them to sb_level1 on the skyblock server.
+#
+# rule3:
+# If the user is a member of the default group, remove them from default, add them to member, and set their primary group
+# to member.
+#
+# WARNING: Unlike internal commands, this system does not ensure that a group exists before adding a user to it.
+# It also does not unsure that a user is a member of a group before making that group their primary group.
+#
+# Before you use "give: group.<name>" or "set-primary-group", make sure that the group exists, and that the user is
+# a member of the group.
+default-assignments:
+#  rule1:
+#    if:
+#      has-true: (<group.vip> | <group.vip+>) & <titles.tilecollector>
+#      has-false: <some.random.permission>
+#      lacks: <prison/group.prison_titlepack>
+#    give:
+#      - prison/group.prison_titlepack

+#      - some.random.permission
