The easiest and quickest way to get started with OpenCache is to use the Vagrant box located in the GitHub project. This is a virtual machine containing all of the tools needed to give OpenCache a spin.
Firstly, run:
git clone https://github.com/opencache-project/opencache-vagrant
This will duplicate the necessary code into a new directory. Next, install Vagrant if you haven't done so already. Finally, start the virtual machine using:
vagrant up
See the README for more details, including the contents of the virtual machine and how best to use it. A more detailed tutorial will be provided shortly; thank you for your patience in the meantime.
