The Makefile works without GOPATH set and without install.tools fine.

The GOPATH layout is created in the Makefile:
mkdir -p "/home/test/cri-o/_output/src/github.com/kubernetes-incubator"
ln -s "/home/test/cri-o" "/home/test/cri-o/_output/src/github.com/kubernetes-incubator"

 ### Get Source Code
 
-As with other Go projects, CRI-O must be cloned into a directory structure like:
-
-```
-GOPATH
-└── src
-    └── github.com
-        └── kubernetes-incubator
-            └── cri-o
-```
-
-First, configure a `GOPATH` (if you are using go1.8 or later, this defaults to `~/go`).
+Clone the source code using:
 
 ```bash
-export GOPATH=~/go
-mkdir -p $GOPATH
-```
-
-Next, clone the source code using:
-
-```bash
-mkdir -p $GOPATH/src/github.com/kubernetes-incubator
-cd $_ # or cd $GOPATH/src/github.com/kubernetes-incubator
 git clone https://github.com/kubernetes-incubator/cri-o # or your fork
 cd cri-o
