Comment 2 for bug 1748855

You could add the info to the following page: https://wl.widelands.org/docs/wl/tutorial/

If the page should get too long, we can split it off afterwards.

I have also hooked the CampaignCreation page into https://wl.widelands.org/wiki/GettingStarted/

Another thing we should document is our policy on numbers ("2" vs. "two" etc.)
