+# All about Data
+
+## Data Cascade
+
+### Data provided by Sissi
+
+### The `_data` subdirectory
+
+### The Frontmatter
+
+## Using data inside templates
+
+Sissi supports a "poor girl's handlebars". It looks for expressions wrapped in double curly braces and replaces them with the data accordingly. If the data is resolved as a function, a parameterless function call will be invoked. If the data results a Promise, it is automatically resolved.
+
+If you place a javascript file named `meta.js` in your _data directory which provides a default export, you can access the object like this:
+
+```js
+export default {
+  author: 'Lea'
+};
+```
+
+```html
+{\{ meta.author }\}
+```
+
+Alternatively, you can put json or yaml into the data directory.
