 In this step you will learn how to create your own custom display filter.

 1. Reset your workspace to Step 9 using:
 
-         git checkout --force step-9

   or

          ./goto_step.sh 9

 In the previous step, the details page displayed either "true" or "false" to indicate whether
 certain phone features were present or not. We have used a custom filter to convert those text
 strings into glyphs: ✓ for "true", and ✘ for "false". Let's see, what the filter code looks like.

 ## Custom Filter

 In order to create a new filter, simply register your custom filter function with the {@link
 angular.filter `angular.filter`} API.

 The name of our filter is "checkmark". The `input` evaluates to either `true` or `false`, and we
 return one of two unicode characters we have chosen to represent true or false (`\u2713` and
-`\u2718`).  
+`\u2718`).

 ## Template
 
+
 Since the filter code lives in the `app/js/filters.js` file, we need to include this file in our
 layout template.

 Filters, like any other component, should be tested and these tests are very easy to write.
