In this example they include `mean` and `quantile`, but `median`, `cdf`, `pmf`, and `sample` are other supported output types.

 ## Directory Structure
 The `hub-config` directory in a modeling hub is required to contain three files:
-   1. `admin.json` - JSON file containing generic information about the hub as well as static configuration settings for downstream tools such as validations, visualizations, etc. This file also contains optional cloud settings for hubs that use cloud storage.
-   2. `tasks.json` - JSON file specifing modeling tasks and model output formats, which may be round-specific.

 ## Recommended Standards  
 Many hubs will use a common set of metadata fields, which we place in the following template schema. Individual hubs may want to add additional metadata fields. These should be selected with the goal of specifying fields that are likely to remain stable across rounds, leaving model attributes that are likely to change across rounds to be described in round-specific abstracts. For consistency across Hubs, we encourage the use of a common set of metadata fields with standard names and definitions. We describe fields that have been used in past Hubs in a second section below the template file.

 ## Template metadata schema file  
 
-The following is a [*template metadata schema file* from the **Example Complex Forecast Hub**](https://github.com/Infectious-Disease-Modeling-Hubs/example-complex-forecast-hub/blob/main/hub-config/model-metadata-schema.json), which is itself drawn from the [**FluSight Forecast Hub**](https://github.com/cdcepi/FluSight-forecast-hub/blob/main/model-metadata/README.md). Many Hubs will use the same fields listed in the *template metadata schema file*, but some may need fewer or more. A Hub's *model metadata schema file* should include either the single combined field `model_id`, or both of the fields `team_abbr` and `model_abbr`. Administrators can remove other fields as needed, and can use [additional optional metadata fields from this list](#optional-additional-metadata-fields). We encourage administrators to use the same standard names and definitions to maintain consistency across Hubs.
