+Open source docxtemplater image module
+==========================================
+This repository holds a updated version of docxtemplater image module.
+
+This package is open source. There is also a [paid version](https://docxtemplater.com/modules/image/) maintained by docxtemplater author.
+
+Note this version is compatible with docxtemplater 3.x.
+
+Installation
+=============
+You first need to install docxtemplater by following its [installation guide](https://docxtemplater.readthedocs.io/en/latest/installation.html#node).
+
+For Node.js install this package
+```
+npm install open-docxtemplater-image-module
+```
+
+For the browser find builds in `build/` directory.
+
+Usage
+=====
+To render an image, your **docx** or **pptx** template should contain the text: `{%image}`
+
+```javascript
+//Node.js example
+var ImageModule = require('open-docxtemplater-image-module');
+
+//Below the options that will be passed to ImageModule instance
+var opts = {}
+opts.centered = false; //Set to true to always center images
+opts.fileType = "docx"; //Or pptx
+
+//Pass your image loader
+opts.getImage = function(tagValue, tagName) {
+    //tagValue is 'examples/image.png'
+    //tagName is 'image'
+    return fs.readFileSync(tagValue);
+}
+
+//Pass the function that return image size
+opts.getSize = function(img, tagValue, tagName) {
+    //img is the image returned by opts.getImage()
+    //tagValue is 'examples/image.png'
+    //tagName is 'image'
+    //tip: you can use node module 'image-size' here
+    return [150, 150];
+}
+
+var imageModule = new ImageModule(opts);
+
+var zip = new JSZip(content);
+var doc = new Docxtemplater()
+    .attachModule(imageModule)
+    .loadZip(zip)
+    .setData({image: 'examples/image.png'})
+    .render();
+
+var buffer = doc
+        .getZip()
+        .generate({type:"nodebuffer"});
+
+fs.writeFile("test.docx",buffer);
+```
+
+Some notes regarding the template:
+* **docx** files: the placeholder `{%image}` must be in a dedicated paragraph.
+* **pptx** files: the placeholder `{%image}` must be in a dedicated text cell.
+
+Centering images
+================
+You can center all images using either passing the option `opts.centered = true` or one by one using `{%%image}` instead of `{%image}` in your templates.
+
+In **pptx** generated documents, images are centered vertically and horizontally relative to the parent cell.
