+# CQL box
+
+Here we provide an easy setup of a small 3 node cassandra cluster on a centos/7 box using vagrant and ansible.
+
+With the currently used centos/7 base box, we faced some issues with the installation of the guest additions on it.
+This failed, such that the ansible directory could not be mounted in the guest os, such that we couldn't provision the box using ansible.
+
+We've worked around it using a simple `yum update`, but it does require multiple `vagrant provision` and a `vagrant reload` call.
+
+TLDR;
+To get a centos box with a 3 node cassandra cluster on it, just run
+
+```bash
+./vagrant_start.sh
+```
