+# .Net library and tool to work with PDF files
+
+## Usage
+
+### VAR.PdfTools
+Add the resulting assembly as reference in your projects, and this line on code:
+
+	using VAR.PdfTools;
+
+Then extract the contents of a data column using:
+
+    var columnData = new List<string>();
+    PdfDocument doc = PdfDocument.Load("document.pdf");
+    foreach (PdfDocumentPage page in doc.Pages)
+    {
+        PdfTextExtractor extractor = new PdfTextExtractor(page);
+        columnData.AddRange(extractor.GetColumn("Column"));
+    }
+    
+Or the content of a field (text on the right of the indicated text):
+
+    var fieldData = new List<string>();
+    PdfDocument doc = PdfDocument.Load("document.pdf");
+    foreach (PdfDocumentPage page in doc.Pages)
+    {
+        PdfTextExtractor extractor = new PdfTextExtractor(page);
+        fieldData.Add(extractor.GetField(txtFieldName.Text));
+    }
+
+### VAR.PdfTools.Workbench
+It is a simple Windows.Forms application, to test basic funcitionallity of the library.

-    various data types are done through the TypeConverter classes 
-    associated with the data types.

-        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
-        <comment>This is a comment</comment>

-                
-    There are any number of "resheader" rows that contain simple 
-    name/value pairs.
-    
-    Each data row contains a name, and value. The row also contains a 
-    type or mimetype. Type corresponds to a .NET class that support 
-    text/value conversion through the TypeConverter architecture. 
-    Classes that don't support this are serialized and stored with the 
-    mimetype set.
-    
-    The mimetype is used for serialized objects, and tells the 
-    ResXResourceReader how to depersist the object. This is currently not 
-    extensible. For a given mimetype the value must be set accordingly:
-    
-    Note - application/x-microsoft.net.object.binary.base64 is the format 
-    that the ResXResourceWriter will generate, however the reader can 
-    read any of the formats listed below.
-    
-    mimetype: application/x-microsoft.net.object.binary.base64
-    value   : The object must be serialized with 
-            : System.Serialization.Formatters.Binary.BinaryFormatter
-            : and then encoded with base64 encoding.
-    
-    mimetype: application/x-microsoft.net.object.soap.base64
-    value   : The object must be serialized with 
-            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
-            : and then encoded with base64 encoding.
-
-    mimetype: application/x-microsoft.net.object.bytearray.base64
-    value   : The object must be serialized into a byte array 
-            : using a System.ComponentModel.TypeConverter
-            : and then encoded with base64 encoding.
