How to install

There are several ways to install ArduinoJson, from simpler to more complex:

1. Use the Arduino Library Manager or equivalent
2. Download ArduinoJson-v6.17.0.h put it in your project folder
3. Download ArduinoJson-v6.17.0.zip and extract it in you libraries folder

Note: ArduinoJson-v6.17.0.h and ArduinoJson-v6.17.0.hpp are almost identical; the difference is that the .hpp keeps everything in the ArduinoJson namespace.
