 ### Style patterns
 
-If you want to use a specific style multiple times you not have to rewrite it for each text, area, or line rule.
+If you want to use a specific style multiple times you not have to rewrite it for each text, line, area or symbol rule.
 If you define a style set an `id` and use it with `use` in your rendering instructions:
  - `style-text`
  - `style-line`
  - `style-area`
+ - `style-symbol`
  
 This example styles all areas with the_residential_ style, which haven't the `highway` or `building` key.

+./gradlew :vtm-web-app:gwtSuperDev

+- Open the link of codeserver: `The code server is ready at http://127.0.0.1:xxxx/`
+
+- Drag the two bookmarklets to your browser's bookmark bar.

+- Visit your [web page](http://localhost:8080/vtm-web-app) and click **Dev Mode On** to start development mode.
