 ### Idea: write examples for official libraries
 
-Many of the official libraries need more examples in order to help users understand how they can be used. Examples are located in the same repository as the library itself.
+Many of the [official libraries](https://github.com/arduino-libraries) need more examples in order to help users understand how they can be used. Examples are located in the same repository as the library itself under the `examples/` directory. If you find a library that has no examples, or insufficient to show its capabilities, that's a good candidate! Make sure you understand what the library does, and what projects it can be used for.
+
+Bonus points to students who also plan to build hardware prototypes that show how the libraries can be used (and document them in [Project Hub](https://create.arduino.cc/projecthub)).

 ### Idea: write MicroPython examples and tools for Portenta
 
-The new [Portenta](https://www.arduino.cc/pro/hardware/product/portenta-h7) board supports [MicroPython](https://micropython.org) in addition to Arduino code. This combination opens up many new opportunities. This task is about writing examples about using MicroPython on a Portenta board.

This combination opens up many new opportunities. This task is about writing examples about using MicroPython on a Portenta board. Any example is welcome: for example, you might show how to use the hardware peripherals from Python, or you might want to port Arduino examples to Python.
