+Documentation
+-------------
+
+All doc links below are for ![GoDoc](https://godoc.org/github.com/huin/goupnp?status.svg).
+
+Supported DCPs (you probably want to start with one of these):
+* [av1](https://godoc.org/github.com/huin/goupnp/dcps/av1) - Client for UPnP Device Control Protocol MediaServer v1 and MediaRenderer v1.
+* [internetgateway1](https://godoc.org/github.com/huin/goupnp/dcps/internetgateway1) - Client for UPnP Device Control Protocol Internet Gateway Device v1.
+* [internetgateway2](https://godoc.org/github.com/huin/goupnp/dcps/internetgateway2) - Client for UPnP Device Control Protocol Internet Gateway Device v2.
+
+Core components:
+* [(goupnp)](https://godoc.org/github.com/huin/goupnp) core library - contains datastructures and utilities typically used by the implemented DCPs.
+* [httpu](https://godoc.org/github.com/huin/goupnp/httpu) HTTPU implementation, underlies SSDP.
+* [ssdp](https://godoc.org/github.com/huin/goupnp/ssdp) SSDP client implementation (simple service discovery protocol) - used to discover UPnP services on a network.
+* [soap](https://godoc.org/github.com/huin/goupnp/soap) SOAP client implementation (simple object access protocol) - used to communicate with discovered services.
+
+
 Regenerating dcps generated source code:
 ----------------------------------------
 
 1. Install gotasks: `go get -u github.com/jingweno/gotask`
 2. Change to the gotasks directory: `cd gotasks`
-3. Download UPnP specification data (if not done already): `wget http://upnp.org/resources/upnpresources.zip`
-4. Regenerate source code: `gotask specgen -s upnpresources.zip -o ../dcps`
+3. Run specgen task: `gotask specgen`
+
+Supporting additional UPnP devices and services:
+------------------------------------------------
+
+Supporting additional services is, in the trivial case, simply a matter of
+adding the service to the `dcpMetadata` whitelist in `gotasks/specgen_task.go`,
+regenerating the source code (see above), and committing that source code.
+
+However, it would be helpful if anyone needing such a service could test the
+service against the service they have, and then reporting any trouble
+encountered as an [issue on this
+project](https://github.com/huin/goupnp/issues/new). If it just works, then
+please report at least minimal working functionality as an issue, and
+optionally contribute the metadata upstream.
