+## Similar Packages
+* [pdf2json](https://www.npmjs.com/package/pdf2json) buggy, no support anymore, memory leak, throws non-catchable fatal errors
+* [j-pdfjson](https://www.npmjs.com/package/j-pdfjson) fork of pdf2json
+* [pdf-parser](https://github.com/dunso/pdf-parse) buggy, no tests

+* [pdf-extract](https://www.npmjs.com/package/pdf-extract) not cross-platform using xpdf
+
+## Installation
+`npm install pdf-parse`
+ 
+## Basic Usage - Local Files
+
+```js
+const fs = require('fs');
+const pdf = require('pdf-parse');
+
+let dataBuffer = fs.readFileSync('path to PDF file...');
+
+pdf(dataBuffer).then(function(data) {
+
+	// number of pages
+	console.log(data.numpages);
+	// number of rendered pages
+	console.log(data.numrender);
+	// PDF info
+	console.log(data.info);
+	// PDF metadata
+	console.log(data.metadata); 
+	// PDF.js version
+	// check https://mozilla.github.io/pdf.js/getting_started/
+	console.log(data.version);
+	// PDF text
+	console.log(data.text); 
+        
+});
+```
+
+## Basic Usage - HTTP
+You can use [crawler-request](https://www.npmjs.com/package/crawler-request) which uses the `pdf-parse`
+
+## Exception Handling
+
+```js
+const fs = require('fs');
+const pdf = require('pdf-parse');
+
+let dataBuffer = fs.readFileSync('path to PDF file...');
+
+pdf(dataBuffer).then(function(data) {
+	// use data
+})
+.catch(function(error){
+	// handle exceptions
+})
+```
+
+## Extend
+* v1.0.9 and above break pagerender callback [changelog](https://gitlab.com/autokent/pdf-parse/blob/master/CHANGELOG)
+* If you need another format like json, you can change page render behaviour with a callback
+* Check out https://mozilla.github.io/pdf.js/
+
+```js
+// default render callback
+function render_page(pageData) {
+    //check documents https://mozilla.github.io/pdf.js/
+    let render_options = {
+        //replaces all occurrences of whitespace with standard spaces (0x20). The default value is `false`.
+        normalizeWhitespace: false,
+        //do not attempt to combine same line TextItem's. The default value is `false`.
+        disableCombineTextItems: false
+    }
+
+    return pageData.getTextContent(render_options)
+	.then(function(textContent) {
+		let lastY, text = '';
+		for (let item of textContent.items) {
+			if (lastY == item.transform[5] || !lastY){
+				text += item.str;
+			}  
+			else{
+				text += '\n' + item.str;
+			}    
+			lastY = item.transform[5];
+		}
+		return text;
+	});
+}
+
+let options = {
+    pagerender: render_page
+}
+
+let dataBuffer = fs.readFileSync('path to PDF file...');
+
+pdf(dataBuffer,options).then(function(data) {
+	//use new format
+});
+```
+
+## Options
+
+```js
+const DEFAULT_OPTIONS = {
+	// internal page parser callback
+	// you can set this option, if you need another format except raw text
+	pagerender: render_page,
+	// max page number to parse
+    max: 0,
+    //check https://mozilla.github.io/pdf.js/getting_started/
+    version: 'v1.10.100'
+}
+```
+### *pagerender* (callback)
+If you need another format except raw text.  
+
+### *max* (number)
+Max number of page to parse. If the value is less than or equal to 0, parser renders all pages.  
+
+### *version* (string, pdf.js version)
+check [pdf.js](https://mozilla.github.io/pdf.js/getting_started/)
+
+* `'default'`
+* `'v1.9.426'`
