CheckBox in kotlin

I saw this code.

with(binding.cbFragmentSettingsUseWifiOnly) {
        isChecked = settings.useWiFiOnly
        setOnClickListener { settings.useWiFiOnly = isChecked }
        binding.clFragmentSettingsUseWifiOnly.setOnClickListener { performClick() }
    }

But, I can't understand this code.
