# Install BigchainDB on a VM with Vagrant

It's quite easy to provision and run a Vagrant VM:

* Install Vagrant in your host system following instructions [here](https://www.vagrantup.com/docs/installation/)
* In your VM-to-be's home directory create the `VagrantFile` and the bash script to provision the machine (`config.sh`)

**VagrantFile**
