+Overview
+********
+
+The CoAP client library allows application to send CoAP requests and parse CoAP responses.
+The application is notified about the response via a callback that is provided to the API
+in the request. The CoAP client handles the communication over sockets.
+As the CoAP client doesn't create socket it is using, the application is responsible for creating
+the socket. Plain UDP or DTLS sockets are supported.
+
+Sample Usage
+************
+
+The following is an example of a CoAP client initialization and request sending:
+
+.. code-block:: c
+
+    static struct coap_client;
+    struct coap_client_request req = { 0 };
+
+    coap_client_init(&client, NULL);
+
+    req.method = COAP_METHOD_GET;
+    req.confirmable = true;
+    req.path = "test";
+    req.fmt = COAP_CONTENT_FORMAT_TEXT_PLAIN;
+    req.cb = response_cb;
+    req.payload = NULL;
+    req.len = 0;
+
+    /* Sock is a file descriptor referencing a socket, address is the sockaddr struct for the
+     * destination address of the request or NULL if the socket is already connected.
+     */
+    ret = coap_client_req(&client, sock, &address, &req, -1);
+
+Before any requests can be sent, the CoAP client needs to be initialized.
+After initialization, the application can send a CoAP request and wait for the response.
+Currently only one request can be sent for a single CoAP client at a time. There can be multiple
+CoAP clients.
+
+The callback provided in the callback will be called in following cases:
+
+- There is a response for the request
+- The request failed for some reason
+
+The callback contains a flag `last_block`, which indicates if there is more data to come in the
+response and means that the current response is part of a blockwise transfer. When the `last_block`
+is set to true, the response is finished and the client is ready for the next request after
+returning from the callback.
+
+If the server responds to the request, the library provides the response to the
+application through the response callback registered in the request structure.
+As the response can be a blockwise transfer and the client calls the callback once per each
+block, the application should be to process all of the blocks to be able to process the response.
+
+The following is an example of a very simple response handling function:
+
+.. code-block:: c
+
+    void response_cb(int16_t code, size_t offset, const uint8_t *payload, size_t len,
+                     bool last_block, void *user_data)
+    {
+        if (code >= 0) {
+	        LOG_INF("CoAP response from server %d", code);
+                if (last_block) {
+                        LOG_INF("Last packet received");
+                }
+        } else {
+                LOG_ERR("Error in sending request %d", code);
+        }
+    }
