-## Notes
+## Advanced Usage and Notes
+
+### Special Considerations
+
+- **Module Limitations**: The `command` module does not support special characters or shell features. For commands requiring shell features (like pipes or redirection), use the `shell` module.
+  
+  Example:
+  ```bash
+  ansible -m shell -a "cat /etc/passwd | grep -l" all -i server.ini --become
+  ```
 
-- **Module Limitations**: The `command` module does not support special characters or shell features. For commands that require shell features (like pipes or redirection), use the `shell` module.
 - **Raw Module**: Use the `raw` module for devices that do not have Python installed. It allows you to execute raw SSH commands directly.
+
+  Example:
+  ```bash
+  ansible -m raw -a "hostnamectl" all -i server.ini --become
+  ```
+
+### Gathering System Facts
+
+Use the `setup` module to gather system facts from all servers:
+
+```bash
+ansible -m setup --become all -i server.ini
+```
+
+You can filter specific facts:
+
+```bash
+ansible -m setup -a "filter=ansible_memory" --become all -i server.ini
+ansible -m setup -a "filter=ansible_distribution" --become all -i server.ini
+```
+
+### Installing Ansible Galaxy Collections
+
+To install the `ansible.posix` collection, use:
+
+```bash
+ansible-galaxy collection install ansible.posix
