+
+## Installation
+
+    npm install pug-linker
+
+## Usage
+
+```js
+var link = require('pug-linker');
+```
+
+### `link(ast)`
+
+Flatten the Pug AST of inclusion and inheritance.
+
+This function merely links the AST together; it doesn't read the file system to resolve and parse included and extended files. Thus, the main AST must already have the ASTs of the included and extended files embedded in the `FileReference` nodes. `pug-load` is designed to do that.
