+## Deploying Wazuh Docker in a Multi-Node Configuration
 
-This deployment is defined in the `multi-node/docker-compose.yml` file with two Wazuh manager containers, three Wazuh indexer containers, and one Wazuh dashboard container. It can be deployed by following these steps:
+This deployment utilizes the `multi-node/docker-compose.yml` file, which defines a cluster setup with two Wazuh manager containers, three Wazuh indexer containers, and one Wazuh dashboard container. Follow these steps to deploy this configuration:
 
-1) Enter the multi-node directory of the repository:
-```
-$ cd multi-node
-```
-2) Increase max_map_count on your host (Linux). This command must be run with root permissions:
-```
-$ sysctl -w vm.max_map_count=262144
-```
-3) Run the certificate creation script:
-```
-$ docker-compose -f generate-indexer-certs.yml run --rm generator
-```
-4) Start the environment with docker-compose:
+1.  Navigate to the `multi-node` directory within your repository:
+    ```bash
+    cd multi-node
+    ```
 
-- In the foregroud:
-```
-$ docker-compose up
-```
+2.  Increase `vm.max_map_count` on each Docker host that will run a Wazuh Indexer container (Linux). This setting is crucial for Wazuh Indexer to operate correctly. This command requires root permissions:
+    ```bash
+    sudo sysctl -w vm.max_map_count=262144
+    ```
+    **Note:** This change is temporary and will revert upon reboot. To make it permanent on each relevant host, you'll need to edit the `/etc/sysctl.conf` file, add `vm.max_map_count=262144`, and then apply the change with `sudo sysctl -p`.
 
-- In the background:
-```
-$ docker-compose up -d
-```
+3.  Run the script to generate the necessary certificates for the Wazuh Stack. This ensures secure communication between the nodes:
+    ```bash
+    docker-compose -f generate-indexer-certs.yml run --rm generator
+    ```
 
+4.  Start the Wazuh environment using `docker-compose`:
 
-The environment takes about 1 minute to get up (depending on your Docker host) for the first time since Wazuh Indexer must be started for the first time and the indexes and index patterns must be generated.
+    * To run in the foreground (logs will be displayed in your current terminal; press `Ctrl+C` to stop):
+        ```bash
+        docker-compose up
+        ```
+    * To run in the background (detached mode, allowing the containers to run independently of your terminal):
+        ```bash
+        docker-compose up -d
+        ```
+
+Please allow some time for the environment to initialize, especially on the first run. A multi-node setup can take a few minutes (depending on your host resources and network) as the Wazuh Indexer cluster forms, and the necessary indexes and index patterns are generated.
