 ### Security and Environment
-
+- **Security** user: root  
 Since the nextflow config is placed in the `$HOME` directory of root, we run the process within the container as `root` **[1]**.
+- **Environement variables**
 Finally we define environment variables to control which pipeline to run **[2]** and create the job definition.
 
-Please set `PIPELINE_URL` to `https://github.com/seqeralabs/nextflow-tutorial.git` and `NF_SCRIPT` to `script7.nf`.
