+## @cmdotcom/text-sdk: A helper library to send messages.
+
+Want to send messages in your Java application? Then you are at the right place.
+If you want to get all the functionalities, go to: [CM.com API Docs](https://docs.cmtelecom.com/bulk-sms/v1.0)
+
+
+## Installing
+
+Add the jar file to your project.
+
+## Instantiate the client
+Use your productToken which authorizes you on the CM platform. Get yours on CM.com
+
+```cs
+MessagingClient client = new MessagingClient("YourproductToken");
+```
+
+## Send a message
+By calling `SendTextMessage` and providing message text, sender name, recipient phone number(s).
+
+```cs
+   MessagingClient client = new MessagingClient("YourProductToken");
+      client.sendTextMessage("Message Text", "TestSender", new String[] {"00316012345678"});
+   
+```
+
+
+## Sending a rich message
+By using the `MessageBuilder` it is possible to create images with media for channels such as WhatsApp and Viber
+```cs
+ MessagingClient client = new MessagingClient("YourProductToken");
+
+ MessageBuilder builder = new MessageBuilder("Message Text", "TestSender", new String[] {"00316012345678"});
+
+ builder.WithAllowedChannels(new Channel[] {Channel.Viber});
+
+    builder.WithRichMessage(new MediaMessage(
+                "cm.com",
+                "https://avatars3.githubusercontent.com/u/8234794?s=200&v=4",
+                "image/png"));
+
+
+       Message message = builder.Build();
+
+       client.sendMessage(message);
+```
