 This directory contains example implementations of `weave` system providers.
 
 ## Providers
-- `avahi_client.cc`
-  - implements: `weave::providerDnsServiceDiscovery`
-  - build-depends: libavahi-client
-  - run-depends: `avahi-daemon`
-- `bluez_client.cc`
-  - not-implemented
-- `curl_http_client.cc`
-  - implements: `weave::provider::HttpClient`
-  - build-depends: libcurl
-- `event_http_server.cc`
-  - implements: `weave::provider::HttpServer`
-  - build-depends: libevhtp
-- `event_network.cc`
-  - implements: `weave::provider::Network`
-  - build-depends: libevent
-- `event_task_runner.cc`
-  - implements: `weave::provider::TaskRunner`
-  - build-depends: libevent
-- `file_config_store.cc`
-  - implements: `weave::provider::ConfigStore`
-- `wifi_manager.cc`
-  - implements: `weave::provider::Wifi`
-  - build-depends: `weave::examples::EventNetworkImpl`
-  - run-depends: `network-manager`, `dnsmasq`, `hostapd`
 
-Note:
-- The example providers are based on `libevent` and should be portable between most GNU/Linux distributions.
-- `weave::examples::WifiImpl` currently shells out to system
-  command tools like `nmcli`, `dnsmasq`, `ifconfig` and `hostpad`.
