+Digital notes about 3rd course of IT Automation with Python on Coursera created by Google
+
+## Course prerequisites
+
+This course requires some familiarity with a few basic operating system concepts like files, directories, and file systems. You'll be using the command line for interacting with Git, so you'll need some familiarity with that as well.
+
+All the examples in this course use Python 3. You'll need a basic grasp of the Python syntax, and the most common data structures and objects. To get the most out of this course, we also strongly recommend that you **install software in your machine**, or have your system administrator install it. You'll need to install Git to follow our examples, and Python 3 to test out the examples.
+
+We'll use Linux for our examples, but you can follow along with Windows or MacOS computers.
