I'm kinda beginner too, so if you have any suggestions or questions feel free to pm

Read the foundry doc, it is very well documented.

I got a foundry project with a xxx.toml or xxx.tlom im not sure , but the lib files are gone . should I get the libs manual or is there a better way to do it

I think if you reinstall the dependencies, the lib folder will be recreated
