+===================
+GENERAL INFORMATION
+===================
+
+This folder contains sample Web applications.
+
+These Web applications make use of NodeJs (http://nodejs.org/). To run
+the applications, you therefore need to install NodeJs on your
+computer. NodeJs acts here as a lightweight, cross-platform Web server
+that statically serves the HTML/JavaScript files and that dynamically
+serves the Orthanc REST API as a reverse proxy (to avoid cross-domain
+problems with AJAX).
+
+Once NodeJs is installed, start Orthanc with default parameters
+(i.e. HTTP port set to 8042), start NodeJs with the sample application
+you are interested in (e.g. "node DrawingDicomizer.js"). Then, open
+http://localhost:8000/ with a standard Web browser to try the sample
+application.
+

+=======================================
+DRAWING DICOMIZER (DrawingDicomizer.js)
+=======================================
+
+This sample shows how to convert the content of a HTML5 canvas as a
+DICOM file, using a single AJAX request to Orthanc.
+
+Internally, the content of the HTML5 canvas is serialized through the
+standard "toDataURL()" method of the canvas object. This returns a
+string containing the PNG image encoded using the Data URI Scheme
+(http://en.wikipedia.org/wiki/Data_URI_scheme). Such a string is then
+sent to Orthanc using the '/tools/create-dicom' REST call, that
+transparently decompresses the PNG image into a DICOM image.
