 Styling a SVG document with CSS for use on the web is most reliably achieved by
 [adding classes to the document and
 embedding](http://css-tricks.com/using-svg/) it inline in the HTML.

+## Sprockets and Webpacker
+
+Inline SVG supports SVGs bundled by either Sprockets or Webpacker, however, be
+aware that the gem will *always* attempt to find SVGs using Sprockts if it is
+enabled.
+
+By default, Inline SVG will use Sprockets to find SVG files if it is enabled in
+your Rails project.
+
+If you have upgraded an older Rails project from Sprockets to Webpacker and you
+no longer want to use Sprockets at all, you should disable the Asset Pipeline
+and Inline SVG will use Webpacker automatically.
+
+If you have both Sprockets *and* Webpacker enabled for some reason and you want
+Inline SVG to use Webpacker to find SVGs then you should configure the
+`asset_finder` appropriately:
+
+```ruby
+InlineSvg.configure do |config|
+  config.asset_finder = InlineSvg::WebpackAssetFinder
 end
 ```
