 # The problem is that to be able to use go get, one needs to put
 # the repository in the $GOPATH. So for example if your gitlab domain
-# is mydomainperso.com, and that your repository is repos/projectname, and
+# is gitlab.com, and that your repository is namespace/project, and
 # the default GOPATH being /go, then you'd need to have your
-# repository in /go/src/mydomainperso.com/repos/projectname 
+# repository in /go/src/gitlab.com/namespace/project
 # Thus, making a symbolic link corrects this.
