+
+This plugin controls the playback of mpris-enabled applications in this device,
+commanded by its counterpart in the other device that acts as a remote control.
+That means both plugins are not symmetrical.
+
+This plugins receives and sends packages with type kdeconnect.mpris.
+
+It keeps a list of detected players it can control via MPRIS. When it receives
+a package that contains the boolean "requestPlayerList" set to true, it will
+send back the list of players in an array named "playerList". If a new player is
+detected or a known one dissappears, it should also send this list. Note that
+players are identified only by its name (its MPRIS Identity), so there can not
+be two players with the same display name.
+
+This plugins also reports the current song, extracted from MPRIS Metadata. It
+should send it when it changes or when receiving a package containing a boolean
+"requestNowPlaying" set to true.
+
+The remote devices can send packages with commands to one of the players. Those
+packages will contain a string "player" with the name of the player they want to
+command and a string "action" with the name of an MPRIS call (like "Play",
+"Next"...).
+
+This plugin can also control the system volume. The peer device can send a
+package with "requestVolume" set to true to ask for the current volume, or send
+a package with "setVolume" set to an integer in the range [0,100] to change it.

kded/plugins/notifications/README

@@ -0,0 +1,32 @@
+
+This plugin listens to packages with type "kdeconnect.notification" that will
+contain all the information of the other device notifications.
+
+The other device will report us every notification that is created or dismissed,
+so we can keep in sync a local list of notifications.
+
+At the beginning we can request the already existing notifications by sending a
+package with the boolean "request" set to true.
+
+The received packages will contain the following fields:
+
+"id" (string): A unique notification id.
+"appName" (string): The app that generated the notification
+"ticker" (string): The title or headline of the notification.
+"isClearable" (boolean): True if we can request to dismiss the notification.
+"isCancel" (boolean): True if the notification was dismissed in the peer device.
+"requestAnswer" (boolean): True if this is an answer to a "request" package.
+
+Additionally the package can contain a payload with the icon of the notification
+in PNG format.
+
+The content of these fields is used to display the notifications to the user.
+Note that if we receive a second notification with the same "id", we should
+update the existent notification instead of creating a new one.
+
+If the user dismisses a notification from this device, we have to request the
+other device to remove it. This is done by sending a package with the fields
+"id" set to the id of the notification we want to dismiss and a boolean "cancel"
+set to true. The other device will answer with a notification package with
+"isCancel" set to true when it is dismissed.
