 This extension uses a host of Go tools to provide the various rich features. These tools are installed in your GOPATH by default. If you wish to have the extension use a separate GOPATH for its tools, provide the desired location in the setting `go.toolsGopath`. Read more about this and the tools at [Go tools that the Go extension depends on](https://github.com/Microsoft/vscode-go/wiki/Go-tools-that-the-Go-extension-depends-on).
