Minikube tutorial bug?

Bug report information

Description

Following the minikube tutorial , I get stuck at step 2, minikube doesn't start.

This seems to be a known issue that minikube 0.26.x doesnt manage to start kubernetes 1.9.0
kubernetes/minikube#2716
kubernetes/minikube#2765

Suggested fix

In minikube.md, provide background for this, and explain that people should use minikube 0.25.2 https://github.com/kubernetes/minikube/releases/tag/v0.25.2

Thank you Laure! Thank you for bringing this up. We found issues with not only the new version of minikube but helm (2.9) as well.

It should be addressed in this PR 😁
