 RenovateBot monitors Tekton bundle references and makes sure that they're up to date. When new versions of the Tekton bundles are available, RenovateBot creates a pull request with the updated references. This gives you time to review, change, and incorporate the new bundles.
 
-== Configuration
-
-Configure RenovateBot through its `renovate.json` configuration file. The following is a sample `renovate.json` file:

-    "$schema": "https://docs.renovatebot.com/renovate-schema.json",
-
-
-    "timezone": "America/New_York",

-Notice the following Tekton items in `renovate.json`: 
-
-<1> `link:https://docs.renovatebot.com/configuration-options/#filematch[fileMatch]`: An array type. RenovateBot parses each string in `fileMatch`, then extracts matching file names from a repository. In this sample, `fileMatch` directs RenovateBot to extract all `.yaml` and `.yml` files in your repository. 
-
-<2> `link:https://docs.renovatebot.com/configuration-options/#pindigests[pinDigests]`: A boolean type. When enabled, RenovateBot pins any Docker images or GitHub actions by means of their `SHA256` digest so that they're immutable.
-
-You can also update `renovate.json` with link:https://docs.renovatebot.com/configuration-options/#[many other options].
