-# rust-mqtt
-Rust native mqtt client for both std and no_std environmnents.
+# Rust-mqtt
+Rust-mqtt is native MQTT client for both std and no_std environments.
+Client library provides async API which can be used with various executors.
+
+## Async executors
+For desktop usage I reccomend using Tokio async executor and for embedded
+you should use Drogue-device
+
+## Building
+```
+cargo build
+```
+
+## Running (on std)
+```
+cargo run
+```
+
+## Contact
+For any information contact me on email <ond.babec@gmail.com>
