 5. Returns the name of the category to sort this badge into (eg. "build"). Used to sort the examples on the main [shields.io](https://shields.io) website. [Here](https://github.com/badges/shields/blob/master/services/categories.js) is the list of the valid categories. See [section 4.4](#44-adding-an-example-to-the-front-page) for more details on examples.
 6. As with our previous badge, we need to declare a route. This time we will capture a variable called `gem`.
-7. We can use `defaultBadgeData()` to set a default `color`, `logo` and/or `label`. If `handle()` doesn't return any of these keys, we'll use the default. Instead of explicitly setting the label text when we return a badge object, we'll use `defaultBadgeData()` here to define it declaratively.

 8. We now jump to the bottom of the example code to the function all badges must implement: `async handle()`. This is the function the server will invoke to handle an incoming request. Because our URL pattern captures a variable called `gem`, our function signature is `async handle({ gem })`. We usually separate the process of generating a badge into 2 stages or concerns: fetch and render. The `fetch()` function is responsible for calling an API endpoint to get data. The `render()` function formats the data for display. In a case where there is a lot of calculation or intermediate steps, this pattern may be thought of as fetch, transform, render and it might be necessary to define some helper functions to assist with the 'transform' step.
 9. Working our way upward, the `async fetch()` method is responsible for calling an API endpoint to get data. Extending `BaseJsonService` gives us the helper function `_requestJson()`. Note here that we pass the schema we defined in step 4 as an argument. `_requestJson()` will deal with validating the response against the schema and throwing an error if necessary.

-10. Upward still, the `static render()` method is responsible for formatting the data for display. `render()` is a pure function so we can make it a `static` method. By convention we declare functions which don't reference `this` as `static`. We could explicitly return an object here, as we did in the previous example. In this case, we will hand the version string off to `renderVersionBadge()` which will format it consistently and set an appropriate color. Because `renderVersionBadge()` doesn't return a `label` key, the default label we defined in `defaultBadgeData()` will be used when we generate the badge.
