-If you have installed Tekton Pipelines using `minimal-release.yaml` or `minimal-release.notags.yaml` and
-wish to add the [built-in remote resolvers](#built-in-resolvers) later, you can install them separately 
-by running the following command:
-
-   ```bash

-To install a specific version, see [Installing Tekton Pipelines on Kubernetes](#installing-tekton-pipelines-on-kubernetes).
