 # scantopdf
 
 A quick bash script that wraps around tesseract and allows tesseract to work on pdfs of scans
+
+## Installation
+To install this script, just paste these commands in the terminal
+```
+git clone https://git.karma-riuk.com/karma/scantopdf /tmp/scantopdf
+sudo cp /tmp/scantopdf/scantopdf /usr/local/bin/scantopdf
+sudo chmod 755 /usr/local/bin/scantopdf
+```
+
+## 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
+```
+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 `"`**
+```
+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.
+```
+scantopdf -v "La Divina Commedia.pdf"
+```
