# Exercise: Getting familiar with nextflow
In this exercise you will run your first nextflow workflow from github, modify
it and see the resume capabilities of nextflow.
### Setup
Create a new directory for workflow execution and change into it
### Run workflow
Execute the hello-world workflow from the ag-computational-bio/nf-hello github repository:
~~~~
nextflow run ag-computational-bio/nf-hello
~~~~
### Question
What files and directories are created in your current directory? What is their purpose?
Hint: Also check for hidden files.
### Modify workflow
Clone the workflow in your current working directory:
~~~~
nextflow clone ag-computational-bio/nf-hello
~~~~
Add additional greetings in the nf-hello/main.nf file.
Rerun the workflow with the -resume option.
~~~~
nextflow run nf-hello -resume
~~~~
### Cleanup
Check your runs with the `nextflow log` command and cleanup all runs with the
`nextflow clean` command.
