Creating the documentation with the essential knowledge (or links)

[raffaeler]

In the triage we observed questions on topics that can be considered essential knowledge to know when interfacing devices and sensors with our library.
We all agreed that it would be important creating one or more documents providing the «essentials» concepts useful for every user. This documentation is meant to collect only the topics that are not related to specific bindings.
These are the topics I suggest to include:

• How to setup and diagnose (this should include how to change the default pins for the peripheral)
  • I2C - https://github.com/dotnet/iot/blob/main/Documentation/raspi-i2c.md
  • SPI - https://github.com/dotnet/iot/blob/main/Documentation/raspi-spi.md
  • PWM - https://github.com/dotnet/iot/blob/main/Documentation/raspi-pwm.md
  • rs232, rs485
• Creating an IoT project (including the CLI/VS alternative procedures).
• Choosing the right driver (libpiod vs sysfs and why)
• How to run the IoT app in a container (a doc on this topic already exists)
• Debouncing a signal (see Jitter on PIN Rising and Falling on GPIO Pin callback #2260 (comment) and other comments). This should not be tied to the Button binding.
• Raspberry Pi 5 docs

Please feel free to add other topics or suggest removing one or more of the above list.
