+Running Code from a Terminal
+============================
+
+In this chapter, you find a recipe to run a Python program from a command line or terminal.
+The recipe focuses on Windows users, because this is where the problem is  most prevalent.
+
+Step 1: Create a project folder
+-------------------------------
+
+Create a new folder for the project.
+In this exammple, name it ``hello``.
+
+Step 2: Create a Python file
+----------------------------
+
+Open your favorite code editor and create a new file ``hello.py``.
+Write a single line into it:
+
+.. code:: python3
+
+   print("hello world")
+
+Store it in the new project folder ``hello``.
+
+
+Step 3: Open a terminal
+-----------------------
+
+Start a new terminal session.
+
+On Windows, search for **Anaconda Prompt** in the Start Menu.
+
+In any case, you should see the text `(base)` at the beginning of the line with the prompt.
+This means Anaconda is installed and the terminal is properly set up for it.
+
+Step 4: Change directory
+------------------------
+
+Use the `cd <folder>` command to switch in the terminal to the new project directory.
+
+On Windows, you can click into the address bar of the browser, copy the complete PATH to your project and paste it right after the `cd` command.
+
+When you type `dir` or `ls`, you should see the contents of the folder.
+
+Step 5: Run the program
+-----------------------
+
+In the same terminal, type:
+
+::
+
+    python hello.py
+
+And you should se the message `hello world` appear.
