the mongo docs seem to be out of date , where can I find more modern docs

I want to learn how to use mongo in general becuase I need a nosql DB in my skill set

so natrually I went to there docs and bookmarked it for later

after some trouble with install the mongo tools becuase I use fadora linux and they didnt make it fully clear to how install it with dnf , but in the end I installed it

I wanted to make a local account to learn the tooling before I try to make a cloud instance but it tells me that the command it outlines in deprecated and will be removed in the next release , and it told me to use atlas local setup

so I did and it seems better than the deprecated version but there is one fatal flaw , is simply doesnt make the project and spits out this error

I googled this and it seems to be a general connection issue with alot more then just mongo

can anyone tell me about documentation that uses the latest version of mongo
