Wiki
A lot of information is available in the Dutch Wiki. The Wiki pages are available in several languages, which you can select that at the top of the page. You can always suggest updates in the Slack channel #team-wazeopedia. Because the guidelines apply to the Netherlands, changes need to be approved first. For more on our Wiki visit our Wiki Wiki page.
Start reading the Wiki at Main page; for editing there is a WME Quick-Start Guide.
