# Configuration

You can use your Quilt catalog's configuration file to show and 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

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.quilt.bio/version-3.5.x/catalog/preferences.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
