-You can customize the following config items:
+```heex
+<.svg name="checkmark" class="foobar" />
+```
+
+## Configuration
 
-* `:path` The path of your svg files relative to your project directory. If using releases, make sure this path is included in your release directory (`priv` is included by default). Defaults to `priv/svgs`.
+* `:otp_app` - The name of your OTP application. This is required.
+* `:as` - The name of the generated component function. Defaults to `:svg`.
+* `:path` - The path of your svg files relative to your project directory. If using releases, make sure this path is included in your release directory (`priv` is included by default). Defaults to `priv/svgs`.
 * `:attributes` - A map of default attributes to inject into the SVG tags. Defaults to `%{}`.
 
-To customize any of these values, add them to `config/config.exs`:
+#### Example
 
 ```elixir
-config :phoenix_svg,
+use PhoenixSVG,
+  otp_app: :myapp,
   path: "priv/static/icons",
   attributes: %{width: "24px", height: "24px"}
 ```
