+# matrix
+
+This is a minimal implementation of the endpoints matrix provides for
+communication inbetween the client and the server.
+
+## Functions
+
+The basic functions availible are described below. I'm pretty sure that I won't
+update these farily often, so you're better of just using `go doc` for
+searching through the functionnns.
+
+### Login
+
+```
+func Login(username, password, homeserver string) (Authinfo, error)
+```
+
+Used to get an authinfo struct containing information needed by other function
+for functioning properly, such as the auth key needed to send messages.
+
+## Send
+
+```
+func Send(authinfo Authinfo, roomID string, message string) error
+func SendImage(authinfo Authinfo, roomID string, image map[string]interface{}) error
+```
+
+Send and message or and image to a room you are in.
+(Sending images is done by providing a map with information on the image:
+
+```
+	image := map[string]interface{}{
+		"msgtype": "m.image",
+		"url":     mxc://matrix.emile.space/askhdlkajshdlkajhdslkjh,
+		"info": map[string]interface{}{
+			"h":        1080,
+			"w":        1920,
+			"mimetype": "image/jpeg",
+			"size":     1337,
+		},
+		"body": "some text associated with the image",
+}
+```
+
+Most important: the url, that actually isn't a url but a mxc URI. To get one
+upload your image using the upload function, you'll get that uri in the
+response.
+
+## Sync
+
+```
+func Sync(authinfo Authinfo) (RespSync, error)
+func SyncPartial(authinfo Authinfo, nextBatch string, eventsChannel chan PackagedEvent) (RespSync, error)
+```
+
+There are two syncs available: `Sync` and `syncPartial`. Sync is used to
+syncronize the first time in order to get all events created. SyncPartial uses
+a token returned by the Sync function to fetch all events created since that
+token was given out (sort of a timestamp).
+
+This allows incremental fetches.
+
+## Upload
+
+```
+func Upload(authinfo Authinfo, filename string, file *bytes.Buffer) (UploadResponse, error)
+```
+
+The upload function uploads the given buffer to the homeserver that is provided
+in the authinfo object. The response contains the mxc URI that can be used to
+send the uploaded image to another participant.
+
