+we *recommend* using [***Vagrant***](https://github.com/docdis/learn-vagrant)
+to run Redis (and your app) in a (Linux) Virtual Machine (VM).
+> We have included a Vagrantfile in this repo which you can use to
+get Redis & Node.js working on ***any*** machine. simply:
+
+```sh
+git clone https://github.com/nelsonic/learn-redis.git && cd learn-redis
+vagrant up
+vagrant ssh
+```
+These three commands will
+1. Clone the repo and move into the new directory
+2. Download and install the Ubuntu VM and latest Redis and Node.js
+(and start Redis server on TCP Port 6379)
+3. SSH into the Vagrant (Ubuntu) VM so you can use the vagrant CLI
+
+
+Boot the VM by running `vagrant up`

+After a few minutes of installing you will see that Redis is running:

+To use Redis from the **command line** log into the VM using `vagrant ssh`:

+Then confirm that the **CLI** is working by issuing the command `redis-cli ping`:

+
+**Note**: If you are *running Linux* on your laptop/dev machine
+and prefer not to have the overhead of running Vagrant
+you can simply **copy** the **installation commands** from the Vagrantfile
+and **paste** them **into** your **terminal**.
