# Config Categories

Config categories are like normal configs except they can be included in other configs or categories. Categories must be annotated with the @Category annotation its only change that is different from a config is that its id is not restricted to being very basic characters.

Config categories unlike entries are added to a config or category via its annotation with categories parameter. Categories are ordered by the way they are put into the annotations list. So if you want category 1 to show up before category 2 have category 1 higher in the list.

The following is an example of how to add categories to a config, this can also be done for a category as it has the same parameter.

```java
@Config(
    value = "demo",
    categories = {
            Category1.class,
            DemoConfig.Category2.class
    }
)
```
