+Alternatively you can use [Vagrant](https://www.vagrantup.com/) environment. To do so, simply [install Vagrant](https://docs.vagrantup.com/v2/installation/index.html) on your machine and execute being inside rqlite repository:
+
+~~~bash
+$ CLUSTER_SIZE=7 vagrant up rqlite
+~~~
+
+This will start Vagrant box and install rqlite with all required dependencies. After this is done, there will be formed a cluster with number of nodes specifed by `CLUSTER_SIZE` variable.
+
+To execute queries against started cluster you can either ssh directly to the Vagrant box via `vagrant ssh rqlite` or execute them from you local box accessing cluster at `192.168.200.10` IP and any port within a range `[4001, 4001 + CLUSTER_SIZE -1]`.
+
+To terminate Vagrant box simply execute:
+
+~~~bash
+$ vagrant destroy rqlite
+~~~
+
 ### Forming a Cluster
 While not strictly necessary to run rqlite, running multiple nodes means the SQLite database is replicated.
