+# Basic cluster environment
+
+This is a environment definition with the required configuration to be prepared to freshly install a Wazuh Indexer
+cluster with two nodes using Vagrant and Libvirt to provision the Virtual Machines.
+
+It also generates the node's required certificates using the `wazuh-certs-tool` and copy them to each node's `home`
+directory, leaving a copy in `test-tools/basic_env`.
+
+
+### Prequisites
+
+1. Download and install Vagrant ([source](https://developer.hashicorp.com/vagrant/downloads))
+2. Install vagrant-libvirt ([source](https://vagrant-libvirt.github.io/vagrant-libvirt/installation.html))
+    > In some cases you must also install `libvirt-dev`
+
+## Usage
+
+1. Navigate to the environment's root directory
+    ```bash
+   cd test-tools/basic_env
+   ```
+2. Initialize the environment
+    ```bash
+   vagrant up
+   ```
+3. Connect to the different systems
+    ```bash
+   vagrant ssh indexer_[1|2]
+   ```
+
+### Cleanup
+
+After the testing session is complete you can stop or destroy the environment as you wish:
+- Stop the environment:
+    ```bash
+    vagrant halt
+    ```
+- Destroy the environment:
+    ```bash
+    vagrant destroy -f
+    ```
