 == EXAMPLE USAGE
 
 It's very simple to use rtesseract:
 
 === CONVERT IMAGE TO STRING
 
   image = RTesseract.new("my_image.jpg")
-  image.to_s #Getting the value
+  image.to_s # Getting the value
 
+=== CONVERT IMAGE TO SEARCHABLE PDF
+
+  image = RTesseract.new("my_image.jpg")
+  image.to_pdf  # Getting the pdf path
+  image.to_s    # Still can get the value only.
+  # ...
+  # some stuff
+  # ...
+  image.clean   # to delete file once finished
+
+This will preserve the image colors, pictures and structure in the generated pdf.
+
 === CHANGE THE IMAGE
 
   image = RTesseract.new("my_image.jpg")
   image.source = "new_image.png"
   image.to_s
