Consider making a video demo of your projects and posting them to your project threads. This could be a screencast or whatever you want.
This is not a hard requirement but it’s a good idea to do it! Show off your hard work! The idea is to have something that you can show to potential future employers to show them how awesome you are.
You may post them to YouTube or Vimeo if you like. I would recommend you put them in your final wrap-up blog posts. To produce them, you can use OBS Studio.
