some might know our Beginners Guide document, which explains how to start with Manjaro Linux. With the focus on Calamares v2.3 a whole section of that PDF file is now outdated. Therefore we need somebody to update that section. You can find the current source here.
If you're not familiar with LaTex, no problem. You can provide us the text in a DOC document or any format you like. However the screenshots should be matching your text effort. Take a look on how we did it in our wiki or in the current document to get a feeling.
We have already updated installation medias with a current version of Calamares. On the layout it shouldn't change, so it is already good to do screenshots.
Feel free to contact us or answer to this thread if you want to help us out.
