# Configuration

You can use your Quilt catalog's configuration file to show or hide certain tabs and buttons in the Quilt catalog. This gives you finer-grained control over how users interact with the Quilt catalog. The catalog config file is per-bucket. The file's path is `s3://BUCKET/.quilt/catalog/config.yaml`.

If there is no config.yaml, or your config.yaml file does not override the `ui` key, then the following defaults are used:

```
ui:
  nav:
    files: True
    packages: True
    queries: True
  actions:
    copyPackage: True
    createPackage: True
    deleteRevision: False
    revisePackage: True
  sourceBuckets:
    s3://BUCKET_1: {}
    s3://BUCKET_2: {}
```

## Properties

* `ui.nav.files: False` - hide Files tab
* `ui.nav.packages: False` - hide Packages tab
* `ui.nav.queries: False` - hide Queries tab
* `ui.actions.copyPackage: False` - hide buttons to push packages across buckets
* `ui.actions.createPackage: False` - hide buttons to create packages via drag-and-drop or from folders in S3
* `ui.actions.deleteRevision: True` - show buttons to delete package revision
* `ui.actions.revisePackage: False` - hide the button to revise packages
* `ui.sourceBuckets` - a dictionary of S3 bucket names that map to an empty object reserved for future enhancements; buckets in this dictionary are the ones offered when the user clicks Revise Package > Add files from Bucket; if the dictionary is not set or is empty the feature "Add files from Bucket" is disabled
* `ui.defaultSourceBucket` - source bucket from `ui.sourceBuckets` that is selected by default; if it doesn't match any bucket then it's ignored
