+in order respect directory hierarchy that match Go package import logic (see
+[How to Write Go Code](https://golang.org/doc/code.html) for more details).
 
-```bash
-export GOPATH=$(realpath ~/workspace_go)
-```

-Clone this repo into your `$GOPATH/src/gerrit.automotivelinux.org/gerrit/src/xds` and use delivered Makefile:

 ```bash
-export GOPATH=${GOPATH}:${ROOTDIR}
+# Declare ROOTDIR, can be any location (for example xds-build)
+ROOTDIR=$HOME/xds-build

 cd xds-server
