 This is a docker machine driver for VMware Fusion and Workstation.
 
-## Build
+## How to consume this driver
+
+### Prerequisite
+Make sure you have VMware Workstation 14 (Windows/Linux) or VMware Fusion 10 (MacOS)
+installed on your machine. Earlier versions of Workstation/Fusion might still work
+with this driver, but it's not officially supported.
+
+### Install
+For MacOS and Linux, make sure `$GOPATH/bin` is part of your `$PATH` for MacOS and Linux.
+For Windows, make sure `%GOPATH%\bin` is included in `%PATH%`.
+
+Run the following command:
+
+```shell
+go get -u github.com/machine-drivers/docker-machine-driver-vmware
+```
+
+if the `PATH` is correctly setup, you will see this if you run the command
+
+```shell
+$ docker-machine-driver-vmware
+This is a Docker Machine plugin binary.
+Plugin binaries are not intended to be invoked directly.
+Please use this plugin through the main 'docker-machine' binary.
+(API version: 1)
+```
+
+### Usage
+The driver can be consumed by `docker-machine`, or potentially other tools that are
+compatible to docker machine drivers like `minikube` (not supported yet). For
+`docker-machine`, create a docker machine is simply a command like this:
 
 ```shell
-make build
+$ docker-machine create --driver=vmware default
 ```
 
+## Difference between driver vmwarefusion
+Docker machine has a builtin driver called `vmwarefusion`. The main difference between
+those drivers is that `vmware` also works on VMware Workstation, while `vmwarefusion` only
+works on VMware Fusion.
