+Hi there :wave: ! 
+
+We are enabling **Infineon PSoC microcontrollers for Arduino** :construction_worker:.
+
+You're a bit early :watch:! We're still working on getting everything ready.
+
+We still need some time until we can provide you with an **ease-of-use** and **enjoyable** Arduino experience with one of **the top-rated microcontrollers** :astonished:.
+
+Meanwhile, you can:
+
+* **Star** :star: this repo to support the project.
+* **Watch** :eyes: it for updates. You'll be the first to know when our first release is available! 
+* Let us know about **ideas** :thought_balloon:, your **wish list** :santa:, or anything you want to **share** with us in the [**discussions**](https://github.com/Infineon/arduino-core-psoc/discussions). 
+
+Thanks for your patience and support :blue_heart:,
+
