-This deployment is defined in the `single-node/docker-compose.yml` file with one Wazuh manager containers, one Wazuh indexer containers, and one Wazuh dashboard container. It can be deployed by following these steps:
+This deployment uses the `single-node/docker-compose.yml` file, which defines a setup with one Wazuh manager container, one Wazuh indexer container, and one Wazuh dashboard container. Follow these steps to deploy it:
 
-1) Enter the single-node directory of the repository:
-```
-$ cd single-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 `single-node` directory within your repository:
+    ```bash
+    cd single-node
+    ```
 
-- In the foregroud:
-```
-$ docker-compose up
-```
-- In the background:
-```
-$ docker-compose up -d
-```
+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, you'll need to edit the `/etc/sysctl.conf` file and add `vm.max_map_count=262144`, then apply with `sudo sysctl -p`.
 
-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.
+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`:
+
+    * 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. It can take approximately a minute or two (depending on your host's resources) as the Wazuh Indexer starts up and generates the necessary indexes and index patterns.
