# guardian: guardian,
# name: "SuperChannel",
# description: "This is the best channel",
# slug: "super-channel",
# threading_enabled: true,

# @option params_to_edit [String,nil] name
# @option params_to_edit [String,nil] description
# @option params_to_edit [String,nil] slug
# @option params_to_edit [Boolean] threading_enabled
