+* The [Examples](https://arduinojson.org/example/?utm_source=github&utm_medium=readme) show how to use the library in various situations.
+* The [API Reference](https://arduinojson.org/api/?utm_source=github&utm_medium=readme) contains the description of each class and function.
+* The [FAQ](https://arduinojson.org/faq/?utm_source=github&utm_medium=readme) has the answer to virtually every question.
+* The [ArduinoJson Assistant](https://arduinojson.org/assistant/?utm_source=github&utm_medium=readme) writes programs for you!
 
-If you run a commercial project that embeds ArduinoJson, think about [sponsoring the library's development](https://github.com/sponsors/bblanchon): it ensures the code that your products rely on stays actively maintained. It can also give your project some exposure to the makers' community.
+---
 
-If you are an individual user and want to support the development (or give a sign of appreciation), consider purchasing the book [Mastering ArduinoJson](https://arduinojson.org/book/)&nbsp;❤, or simply [cast a star](https://github.com/bblanchon/ArduinoJson/stargazers)&nbsp;⭐.
+Do you like this library? Please [star this project on GitHub](https://github.com/bblanchon/ArduinoJson/stargazers)!
+
+What? You don't like it but you *love* it?
+We don't take donations anymore, but [we sell a book](https://arduinojson.org/book/?utm_source=github&utm_medium=readme), so you can help and learn at the same time!
