+# Ember skeleton #
+
+[![Build Status](https://secure.travis-ci.org/dockyard/ember-skeleton.svg?branch=master)](http://travis-ci.org/dockyard/ember-skeleton)
+
+## About ##
+
+Show fast-loading temporary images in place of an eventual slow-loading
+image.
+
+## Building yourself ##
+
+```bash
+npm install && bower install
+ember build
+```
+
+The builds will be in the `dist/` directory.
+
+## Installing ##
+
+`ember install ember-skeleton`
+
+## Looking for help? ##
+
+If it is a bug [please open an issue on GitHub](https://github.com/dockyard/ember-skeleton/issues).
+
+## Usage ##
+
+Simply use the component in your templates:
+
+```hbs
+{{skeleton-img src="/path/to/large/image.png" tmpSrc="/path/to/small/placeholder.png"}}
+```
+
+The workflow is thus:
+
+1. The `tmpSrc` image will be loaded first
+2. Once complete the `src` image will attempt to load
+3. If the `src` completes successfully it will be displayed
+4. If the `src` does not complete successfully the `tmpSrc` will stay
+5. If an optional `errorSrc` is provided that image will be displayed in
+   the even of `src` not completing successfully.
+
+### Error Example ###
+
+```hbs
+{{skeleton-img src="/path/to/invalid/large/image.png" tmpSrc="/path/to/small/placeholder.png" errorSrc="/path/to/error/placeholder.png"}}
+```
