 A great addition, especially if you connect to SDF on a color terminal, is nano's use of “syntax” files, which provide syntax highlighting for several programming languages and related filetypes, such as HTML files, shell scripts, shell resource files (like ''.bashrc'') and even the nano resource file ''.nanorc'', where the settings for syntax file are kept.
+====Using GNU Nano====
+It's quite easy to use Nano to write anything you want.
+To run Nano, enter in the terminal:
+<code bash>nano</code>
+You can indicate the name and extension of the file you want to edit:
+<code>nano file.txt</code>
+In the top bar you will find the version of the program, the name of the loaded file (if we have not loaded anything it will say “new buffer”). It will also inform you if the file has been modified with respect to the original loaded.
+The main commands to unleash the potential of Nano are activated by using the Control key, which is abbreviated in Nano with the circumflex symbol (''^''). For example, to save a file, Nano tells us that the key combination to use is “^O”, so we press Ctrl+o.
+^Result^ Shortcut^
+|Cut (current line or region)| Ctrl+k |
+|Paste |Ctrl+u |
+|Find |Ctrl+w |
+|Justify paragraph |Ctrl+j |
+|Justify all |Esc,AltGr+j |
+|Undo |Esc,AltGr+u |
+|Redo |Esc,AltGr+e |
+|Line numbering |Esc,AltGr+n |
+|Save |Ctrl+o |
+|Switch nano to background and return to the shell. Use fg to return to nano. |Ctrl+t,Ctrl+z |
+|**Exit Nano** |Ctrl+x|
+To search for a text string, use **Ctrl+w**. With **Ctrl+j** will justify a long paragraph in several short lines (although it is not used in configuration files, it is very useful in any common text).
+With **Ctrl+G** or **F1** will provide Help screens with the rest of the commands. To exit Nano press Ctrl+x.
+We also find the //Meta commands// (or “metas”, abbreviated in Nano with ''M-''). On PC, you may access these Metacommands  by pressing **Escape key** and **AltGr**, followed by the meta letter.
+For example, to add right indentation to a paragraph is shown as ''M-}''. Therefore, on a PC keyboard press **Esc,AltGr+}** to indent the paragraph.
+Once you are familiar with Nano, you can get a less cluttered screen by removing its title bar with **Shift+Alt+z** and the help bar with **Shift+Alt+x**.
+===Nano Configuration===
+To configure Nano you can directly edit the ''~/.nanorc'' file.
