# but we actually want it to under the correct expected package in the GOPATH (/go)
# - Create the directory to host the code that matches the expected GOPATH package locations
# - Use /go as the default GOPATH because this is what the image uses
# - Link our current directory (containing the source code) to the package location in the GOPATH
