The documentation of KiCad is sadly out of date in many places. This is the result of too few volunteers to take care of it. It is a well known problem that can only get better if users are prepared to help out once they can. How can I help improve KiCad?
All of this is made worse by many tutorials being made for version 4 still showing up near the top of search results. Sadly it is not always the case that tutorial authors clearly list the version they are valid for on every page of the tutorial so it might be easy to miss the fact that it is for a different version.
And of course the topic of version 5.0 versus 5.1 which had massive user interface differences with only a minor number changing in the version string. this can easily be missed by newcomers.
The good news is that there are up to date resources out there. Our forum FAQ ((Start Here) Frequently Asked Questions) has a lot of resources created by a small number of forum members.
