+  New versions of 'Raspberry Pi OS' includes Python. You can check that 
+  Python is installed with the command:

+
+  New versions of Ubuntu includes Python 3. You can choose between use `python3`
+  command or to install Python 2 (that includes `python` command).
+  
+  
+  If you prefer to use Python 3, in the next installation block, you must update
+  `pialert.cron` file with the correct command: `python3` instead of `python`.
+  ```
+  python3 -V
+  ```
+
+4.4 - If Python is not installed in your system, you can install it with this
