+#### Configuring a pipeline
+```bash
+Usage: cirro create-pipeline-config [OPTIONS]
+
+  Create pipeline configuration files
+
+Options:
+  -p, --pipeline-dir DIRECTORY  Directory containing the pipeline definition
+                                files (e.g., WDL or Nextflow)  [default: .]
+  -e, --entrypoint TEXT         Entrypoint WDL file (optional, if not
+                                specified, the first WDL file found will be
+                                used). Ignored for Nextflow pipelines.
+  -o, --output-dir TEXT         Directory to store the generated configuration
+                                files  [default: .cirro]
+  -i, --interactive             Gather arguments interactively

+
+It is highly recommended that:
+- Nextflow pipelines utilize a [`nextflow_schema.json`](https://nextflow-io.github.io/nf-schema/latest/nextflow_schema/nextflow_schema_specification/) file. (If your pipeline originates from [NF-Core](https://nf-co.re/), this should already be the case.)
+- WDL pipelines are defined in WDL v1.0 or higher and explicitly define an `input` section in the root-level workflow.
+
 ### Interactive Commands
 
 When running a command, you can specify the `--interactive` flag to gather the command arguments interactively.
