+\page page_config Configuration
+
+One of the design goals of PipeWire is to be able to closely control
+and configure all aspects of the processing graph.
+
+A fully configured PipeWire setup runs various pieces, each with their
+configuration options and files:
+
+- **pipewire**: The PipeWire main daemon that runs and coordinates the processing.
+
+- **pipewire-pulse**: The PipeWire PulseAudio replacement server. It also configures
+  the properties of the PulseAudio clients connecting to it.
+
+- **wireplumber**: Most configuration of devices is performed by the session manager.
+  It typically loads ALSA and other devices and configures the profiles, port volumes and more.
+  The session manager also configures new clients and links them to the targets, as configured
+  in the session manager policy.
+
+- **PipeWire clients**: Each native PipeWire client also loads a configuration file.
+  Emulated JACK client also have separate configuration.
+
+# Configuration Settings
+
+Configuration of daemons:
+
+- [PipeWire daemon configuration](https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Config-PipeWire)
+- [WirePlumber daemon configuration](https://pipewire.pages.freedesktop.org/wireplumber/)
+- [PipeWire PulseAudio daemon configuration](https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Config-PulseAudio)
+
+Configuration of devices:
+
+- [WirePlumber configuration](https://pipewire.pages.freedesktop.org/wireplumber/daemon/configuration.html)
+- [Device runtime settings](https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Config-Devices)
+
+Configuration for client applications, either connecting via the
+native PipeWire interface, or the emulated ALSA, JACK, or PulseAudio
+interfaces:
+
+- [PipeWire native clients](https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Config-client)
+- [PipeWire ALSA clients](https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Config-ALSA)
+- [PipeWire JACK clients](https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Config-JACK)
+- [PipeWire PulseAudio clients](https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Config-PulseAudio)
