+Adds support for Astro.resolve
+
+`Astro.resolve()` helps with creating URLs relative to the current Astro file, allowing you to reference files within your `src/` folder.
+
+Astro *does not* resolve relative links within HTML, such as images:
+
+```html
+<img src="../images/penguin.png" />
+```
+
+The above will be sent to the browser as-is and the browser will resolve it relative to the current __page__. If you want it to be resolved relative to the .astro file you are working in, use `Astro.resolve`:
+
+```astro
+<img src={Astro.resolve('../images/penguin.png')} />

 ## `getStaticPaths()`
 
 If a page uses dynamic params in the filename, that component will need to export a `getStaticPaths()` function.
