Hey @sangfrois ! As you can see I've been organizing the repo a little bit to make sure we don't miss any task. I'm assigning you this issue because we already merged the PR this was mentioned in.

I've created a project board to have a clear view of what's to-do, in progress and done for the first version of the website. If you think electrodermal activity should be part of the first version, please add this issue and its corresponding PR to the project! 😉
