+# Linux test setup with Vagrant
+
+This is an example setup, based on vagrant + virtualbox, that allows to easily run ansible commands to test the module.
+
+## Requirements
+
+- vagrant > 2.0.0
+- virtualbox > 5.1.28
+
+## Setup
+
+Run the Vagrantfile defined in `ansible-datadog/manual_tests`:
+
+- provision VM: `vagrant up`
+- connect to the VM to check the configuration: `vagrant ssh`
+- when done, destroy VM when needed: `vagrant destroy -f`
+
+- From `ansible-datadog`'s parent directory, run:
+
+```shell
+ansible-playbook ansible-datadog/manual_tests/test_7_full.yml -i ansible-datadog/manual_tests/inventory
+```
+
+Note: Replace `test_7_full.yml` with any of the other yaml files on this directory.
+Note: If getting access denied errors, make sure Vagrant is forwarding the VM port 22 to the local port 2222. If using a different port, update the 'inventory' file
+
+# Windows test setup from WSL
+
+## Requirements
+
+- Install Ansible and `pywinrm` inside WSL: `sudo python3 -m pip install  ansible pywinrm`
+- From an elevated Powershell terminal (outside WSL), run the following script to setup WinRM so Ansible can connect:
+https://raw.githubusercontent.com/ansible/ansible/devel/examples/scripts/ConfigureRemotingForAnsible.ps1
+- Make sure the Administrator account is enabled and you know the password (or use a different account in the `inventory_win` file).
+
+## Setup
+
+- From `ansible-datadog`'s parent directory, run in a WSL console (it will ask for the Administrator password each time):
+
+```shell
+ansible-playbook -k ansible-datadog/manual_tests/test_7_full.yml -i ansible-datadog/manual_tests/inventory_win
+```
+
+Note: Replace `test_7_full.yml` with any of the other yaml files on this directory.
