+### Run Linux Commands with Loz
+Loz empowers users to execute Linux commands using natural language. This feature bridges the gap between intuitive language and technical command execution, making Linux more accessible to a broader audience. Below are some examples demonstrating how `loz` translates natural language into Linux commands:
+
+#### Examples
+- Find the largest file in the current directory:
+  ```
+  loz "find the largest file in the current directory"
+  -rw-rw-r-- 1 foo bar 9020257 Jan 31 19:49 ./node_modules/typescript/lib/typescript.js
+  ```
+
+- Check if Apache2 is running:
+  ```
+  loz "check if apache2 is running on this system"
+  ● apache2.service - The Apache HTTP Server
+  ```
+
+- Detect GPUs in the system:
+  ```
+  loz "Detect GPUs on this system"
+  00:02.0 VGA compatible controller: Intel Corporation Device a780 (rev 04)
+  ```
+
+#### Caution
+To prevent unintentional system modifications, avoid running commands that can alter or remove system files or configurations, such as `rm`, `mv`, `rmdir`, or `mkfs`.
+
+#### Safe Mode
+To enhance security and avoid unintended command execution, loz can be run in Safe Mode. When activated, this mode requires user confirmation before executing any Linux command.
+
+Activate Safe Mode by setting the LOZ_SAFE=true environment variable:
+```
+LOZ_SAFE=true loz "Check available memory on this system"
+```
+Upon execution, loz will prompt:
+```
+Do you want to run this command?: free -h (y/n)
+```
+Respond with 'y' to execute the command or 'n' to cancel. This feature ensures that you have full control over the commands executed, preventing accidental changes or data loss.
+
 ### Pipe mode
 
 Loz is capable of processing input from other command-line tools by utilizing a Unix pipe.
