+## Working with forms
+
+By listening to the `blur` function of codemirror you can ensure, that the value of the underlying textarea in your form always corresponds to the value of your SimpleMDE and vice versa.
+
+```JavaScript
+var textarea = $("#MyID");
+var simplemde = new SimpleMDE({element: textarea[0]});
+simplemde.value(textarea.text());
+simplemde.codemirror.on("blur", function() {
+   textarea.text(simplemde.value());
+});
+```

 ## Configuration
 
 - **autoDownloadFontAwesome**: If set to `true`, force downloads Font Awesome (used for icons). If set to false, prevents downloading. Defaults to `undefined`, which will intelligently check whether Font Awesome has already been included, then download accordingly.
