+Cookie Utils permission system uses groups for assigning permissions.
+
+Plugin will always try to create permission group called `default` if it doesn't exist already, file with name `default.json` in location `server_folder/perm_groups/` will always have id `default`.
+Default groups is one that is used for players that don't have group assigned by authorized person.
+
+Each user can have assigned at max 1 group.
+
+Group json file needs to contain:
+- `group_id` - unique string without spaces that will be used for assigning that group to users via cmd.
+- `group_DisplayName` - Display Name for the group, it can contain spaces.
+- `group_Desc` - Description of group, you can place here.
+- `perms` - Array of strings of permissions, some commands might require specifing advance perms like `main_perm.sub_perm.next_sub_perm`.
+
+> **Note** 
+> The `*` can be used to give access to all cmds and or all sub permissions of any permission.
