+
+## Usage
+
+To use this script, follow this steps
+1. Open a terminal
+2. Go the location of the file you want to "convert" with the following command
+    ```bash
+    cd <path>
+    ```
+    where `<path>` is the location of the **folder** where lies the file to convert.
+3. Use the command `scantopdf` and give it, as an argument, the file you want to
+    convert.  
+    If the file name contains **spaces**, surround it with **quotes** `"`
+    ```bash
+    scantopdf "I Promessi Sposi.pdf"
+    ```
+    Optionally you can give it the `-v` flag (before the name of the file), to make
+    the script verbose, so instead of doing its job without saying anything, it will
+    print each step that it's doing.
+    ```bash
+    scantopdf -v "La Divina Commedia.pdf"
+    ```
+
+4. You can open the converted pdf with whatever application you want, its name
+   will be the same as the old one, but with " - EDITABLE" at the end.
