 You can set labels for your workflow to select an agent to execute the workflow on. An agent will pick up and run a workflow when **every** label assigned to it matches the agents labels.
 
-To set additional agent labels check the [agent configuration options](../30-administration/15-agent-config.md#woodpecker_filter_labels). Agents will have at least four default labels: `platform=agent-os/agent-arch`, `hostname=my-agent`, `backend=docker` (type of the agent backend) and `repo=*`. Agents can use a `*` as a wildcard for a label. For example `repo=*` will match every repo.

-### Alternate Names
-
-There may be scenarios where you are required to store secrets using alternate names. You can map the alternate secret name to the expected name using the below syntax:
-
-```diff
- steps:
-   - name: docker
-     image: plugins/docker
-     repo: octocat/hello-world

 ### Use in Pull Requests events
 
 Secrets are not exposed to pull requests by default. You can override this behavior by creating the secret and enabling the `pull_request` event type, either in UI or by CLI, see below.
