+# Cloud Proxy Service
+
+## Overview
+
+*Cloud proxy service* provides possibility to send and receive data to/from clouds.
+
+It is allowed to use *Cloud proxy service* from several application.
+The messages/events separtion between application is done within service.
+
+## Verbs
+
+```
+| Name               | Description                             | Data                                                |
+| ------------------ |:----------------------------------------|:----------------------------------------------------|
+| sendMessage        | send data to the cloud                  | application ID, JSON {"data":"message content"}     |
+| subscribe          | subs. for particular application id     | application ID extracted from msg                   |
+| unsubscribe        | unsubs. for particular application id   | application ID extracted from msg                   |
+| ping               | verify connectivity to service          | N/A                                                 |
+```
+## Events
+
+```
+| Name                         | Description                                             |
+| ---------------------------- |:--------------------------------------------------------|
+| sendMessageConfirmation      | confirmation from cloud for previously sent message     |
+| receivedMessage              | message from cloud to be propagated to the application  |
+```
+
+## Configuration
+
+Cloud proxy service requires configuration of the cloud to be used. Configuration is stored in the **config.ini** file.
+
+By default the configuration file **config.ini** is searched stored in
+
+* $AFM_APP_INSTALL_DIR/etc/config.ini  - **default one**
+* /etc/cloudproxy-service/etc/config.ini
+
+At the moment only Azure cloud is supported.
+
+### Azure configuration
+The configuration has to contain the connection string for device: **DeviceConnectionString** in
+section **[AzureCloudConnection]**
+
+```
+[AzureCloudConnection]
+DeviceConnectionString=My=Azure=Device=Connection=String
+```

+# Test cloud applications #
+
+## Description
+
+The test-cloud-app and telemetry-cloud-app are examples of an agl-cloudproxy-service client.
+They are used to demonstrate the possibilities of the cloudproxy service.
+
+## Applications
+
+* test-cloud-app: Simple application demonstrating the following possibilities:
+    * Sending the messages to cloud over cloud proxy server
+    * Receiving confirmations from cloud on the sent messages
+    * Receiving messages from cloud
+
+
+* telemetry-cloud-app: Application which sends the GPS coordinates to the cloud
+    * Sending of the messages with telemetry to the cloud
+    * Receiving of the messages from the cloud
+
+Applications use CloudProxy client as high level interface for the messages sending and receiving
+
+## CloudProxy client
+
+CloudProxy client hides the communication with CloudProxy server. It incupsulates the following actions
+
+* Connection to **cloudporxy** over wsj1 websocket
+* Subscription to the event
+* Event loop handling
+
+**Note:** At the moment only two event types are supported
+1. Event_SendMessageConfirmation
+2. Event_ReceivedMessage
+
+### Usage of a Cloudproxy client:
+
+* Include the appropriate header to appliciation
+
+ ```
+ #include "cloudproxy-client/cloudproxyclient.h"
+  ```
+
+* Initialization of the CloudProxy client inside the application:
+
+```
+CloudProxyClient* g_cloudproxyclient{nullptr};
+
+g_cloudproxyclient = new CloudProxyClient();
+g_cloudproxyclient->init(port, token.c_str());
+
+```
+
+### Message handling from/to the CloudProxy server:
+
+
+* Subsription to the Event_SendMessageConfirmation
+
+
+
+```
+g_cloudproxyclient->set_event_handler(CloudProxyClient::Event_SendMessageConfirmation, [](json_object* object){
+                                json_object *j_result;
+                                if(!json_object_object_get_ex(object, "result", &j_result))
+                                {
+                                        qDebug("Can't read confirmation result");
+                                        return;
+                                }
+
+                                qDebug("Confirmation result %d", (int)json_object_get_boolean(j_result));
+        });
+
+   ```
+
+
+
+* Subsription to the Event_SendMessageConfirmation
+
+```
+g_cloudproxyclient->set_event_handler(CloudProxyClient::Event_ReceivedMessage, [](json_object* object)
+                                json_object *event_data;
+                                const char* data_str{nullptr};
+                                if(!json_object_object_get_ex(object, "data", &event_data) ||
+                                    data_str = json_object_get_string(event_data)) == nullptr)
+                                {
+                                        qDebug("Can't read event data");

+                                }
+
+                                qDebug("Received data: %s", data_str);
+        });
+   ```
+
+
+* Message sending:
+
+
+```
+qDebug() << "sendMessage result: " << g_cloudproxyclient->sendMessage("{\"app_key\": \"app_value1111\"}");
