 An instance of `FillablePDF` has the following methods at its disposal:
 
 ```ruby
-pdf.get_field('full_name')
+pdf.has_fields? # returns true if the form has any fillable fields
 
-pdf.set_field('first_name', 'Richard')
+pdf.num_fields # get the total number of fillable form fields
 
-pdf.set_fields({first_name: 'Richard', last_name: 'Rahl'})
+pdf.get_field('full_name') # retrieve a single field value by field name
+
+pdf.set_field('first_name', 'Richard') # set a single field
+
+pdf.set_fields({first_name: 'Richard', last_name: 'Rahl'}) # set multiple fields
 ```
 
 Once the PDF is filled out you can either overwrite it or save it as another file:
 
 ```ruby
 pdf.save
 
-pdf.save_as(file)
+pdf.save_as('output.pdf')
 ```
 
 Or if you prefer to flatten the file (i.e. make it non-editable), you can instead use:
 
 ```ruby
 pdf.save(true)
 
-pdf.save_as(file, true)
+pdf.save_as('output.pdf', true)
 ```
