 The typical command for running the pipeline is as follows:
 
-```bash
+```console
 nextflow run nf-core/fetchngs --input ids.txt -profile docker
 ```
 
 This will launch the pipeline with the `docker` configuration profile. See below for more information about profiles.
 
 Note that the pipeline will create the following files in your working directory:
 
-```bash
+```console

 When you run the above command, Nextflow automatically pulls the pipeline code from GitHub and stores it as a cached version. When running the pipeline after this, it will always use the cached version if available - even if the pipeline has been updated since. To make sure that you're running the latest version of the pipeline, make sure that you regularly update the cached version of the pipeline:
