The platform for the training is Notion:

Create an account with your EU email address: instructions

You will be added as a guest to the training materials. This will allow you to:

  • find all the training materials and links easily
  • add comments and questions
  • submit assignments

All module pages have a link to the next module at the bottom, and a link to the overview page

Track your progress by duplicating the track your progress page (create a private workspace and then click the Duplicate link in the top navigation)

You have comment permissions on all pages, so you can add questions directly in the pages (you can mention me with "@Maarten Lambrechts")

You have edit permissions on the assignment pages, so you can add your submission directly to these pages

Extra practicality for this training: installing a screen reader

Try to follow the instructions in the Getting started with ChromeVox section of the Accessible HTML module

If you have issues, add them as comments in that section
