What did you do?

Successfully visited the Go docs for the installation process.

What did you see happen?

I saw no mention of adding $GOBIN to $PATH, which is assumed for some of the packages from the Go project.

What did you expect to see?

Many of the commands belonging to packages in the Go project repos (like pkgsite, bent, govulncheck, among others) seem to assume that users have added $GOBIN to their $PATH, providing usage instructions based on just that.

Thing is, with the exclusion of docs for installing Go from source, I haven't seen this suggested or mentioned neither in the installation docs nor in the output of go help install.

I strongly believe that, especially for people starting out with the language, it's not immediately obvious that those commands would be, by default, installed into $GOBIN - which, in my opinion, is not terribly problematic, as long as we get some kind of a hint regarding adding $GOBIN to the $PATH. This would also compliment the package documentation pretty nicely, with things working out of the box when following instructions in the aforementioned packages description.

I did have a short conversation in the go-nuts Google group about this before deciding to file an issue, so I do hope I'm not the only one that change would make sense to. In terms of the context of that discussion, I think a simple mention of the matter in the installation docs would probably go a long way.

Thanks in advance!
