-# Python systems programming
+# Hands-on
 
-This repository contains material for a training on how to do systems
-programming using Python.  The notebooks can be executed on
-[Google Colab](https://colab.research.google.com/).
+Jupyter notebooks to use during the hands-on sessions:
 
-Python is a very versatile programming language that has a wide range of
-applications.  This training concentrates on interaction with the
-operating system, the file system, other applications and the network.
-This is useful for systems programming, but also when you want to use
-Python as a coordination language for your workflows.
-
-Subjects and Python modules that will be covered:
-
-  * interacting with the operating system: os, platform, sys, psutil
-  * interacting with the filesystem: os.path, pathlib, shutil,
-    fileinput, tempfile
-  * running & communicating with other processes: sh, subprocess
-  * command line arguments & configuration files: argparse, configparser
-  * compressing & decompressing files: e.g., gzip, tarfile
-  * running remote commands using SSH: paramiko
