 # ansible-playground
 
+This collection includes tasks to configure SSH and add local user accounts. It verifies the SSH configuration and creates the specified users with specific attributes.
+
+## Usage
+
+### 1. Install the Collection
+
+```bash
+ansible-galaxy collection install git+https://git.slc.ar/slococo/ansible-playground.git#/slococo/playground
+```
+
+### 2. Create an inventory file
+
+Create an inventory file (e.g., `inventory`) with the following content:
+
+```
+[all]
+target_host ansible_host=<IP_ADDRESS_OR_HOSTNAME> ansible_user=<USERNAME> ansible_connection=ssh ansible_ssh_private_key_file=<PRIVATE_KEY_PATH>
+```
+
+Replace `<IP_ADDRESS_OR_HOSTNAME>` with the IP address or hostname of your target host, `<USERNAME>` with the SSH username, and `<PRIVATE_KEY_PATH>` with the path to the SSH private key file.
+
+### 3. Run the Playbook
+
+```bash
+ansible-playbook -i inventory slococo.playground.main
+```
+
+### Expected outcome
+
+Upon successful execution, the playbook will:
+
+- Create the users `local_adm` and `local_log` with the specified attributes.
+- Verify the SSH configuration with the provided settings:
+  - `PasswordAuthentication`: yes
+  - `PermitEmptyPasswords`: no
+  - `PermitRootLogin`: no
+
+### User configuration
