+PDF Fill Form (**pdf-fill-form**) is Node.js native C++ library for filling PDF forms. Created PDF file is returned back as Node.js Buffer object for further processing or saving - *whole process is done in memory*. Library offers methods to return filled PDF also as PDF file where pages are converted to images.
 
 Libary uses internally Poppler QT4 for PDF form reading and filling. Cairo is used for PDF creation from page images (when parameter { "save": "imgpdf" } is used). 
+##Features
+* Supports reading and writing the following PDF form field types: TextField and Checkbox 
+* You can write following files:
+	* PDF
+	* PDF where pages are converted to images
+* All the work is done in memory - no temporary files created
+* Results are returned in Node.js Buffer -object
+* Not using the PDFtk -executable - instead we use the Poppler library
+
 ##Examples
+###Using promises
+```javascript
+var pdfFillForm = require('pdf-fill-form');
+
+pdfFillForm.read('test.pdf')
+.then(function(result) {
+    console.log(result);
+}, function(err) {
+	console.log(err);
+});
+```
+```javascript
+var pdfFillForm = require('pdf-fill-form');
+var fs = require('fs');
+
+pdfFillForm.write('test.pdf', { "myField": "myField fill value" }, { "save": "pdf" } )
+.then(function(result) {
+	fs.writeFile("test123.pdf", result, function(err) {
+		if(err) {
+	   		return console.log(err);
+	   	}
+	   	console.log("The file was saved!");
+	}); 
+}, function(err) {
+  	console.log(err);
+});
