+## Dev environment
+
+For dev and testing purpose, a vagrant environment is provided.
+
+For now, the only vagrant provider supported is libvirt and only usable on Linux machines.
+
+### Initialize environment
+
+To setup the initial environment:
+
+```shell
+vagrant init-warewulf
+```
+
+This command creates three VM nodes:
+* wwctl
+* wwnode1
+* wwnode2
+
+On `wwctl` node, the latest stable warewulf release available will be installed and
+automatically adds `wwnode1`/`wwnode2` respectively as `n1` and `n2` in warewulf.
+
+Once initialized, you can use `vagrant up` and `vagrant halt` to start/stop VM's as usual.
+
+### Cleanup environment
+
+To cleanup the environment:
+
+```shell
+vagrant cleanup-warewulf
+```
+
+This command stops VM nodes and deletes them
+
+### Power control
+
+`wwnode1` and `wwnode2` can be started/stopped from `wwctl` node via commands:
+
+```shell
+wwctl power on n1
+wwctl power on n2
+```
+
+```shell
+wwctl power off n1
+wwctl power off n2
+```
+
+### Alpine boot test
+
+For a quick test/demo, an alpine boot script is provided, you can run it with:
+
+```shell
+vagrant ssh wwctl -c "sudo ./alpine-boot.sh"
+```
