+# About
+If your `$GOROOT` is in `~/goroot` and your `$GOPATH` is in `~/go`, you want to make sure that your new go version goes to the right folder.
+By default the go tar file will unpack with `go/` as a prefix directory, thus we want to remove that when unpacking, thus the `--strip-components=1`.
+
+```bash
+tar -C ~/goroot -xzvf go$VERSION.linux-amd64.tar.gz --strip-components=1
+```
