 1. `.git` contains all files related to `git`. These files are usually not interesting, unless you need to go back to old commits or want to know more details. Best leave this alone. For a detailed description of how `git` (and with it the `.git` directory) works, see [`git` description](##Git).
 2. `.vscode` contains all files relevant for environment setup to run this project in [Visual Studio Code](https://code.visualstudio.com/). These files are:
     1. `settings.json`: the setup file to set up VS Code in the desired configuration. Feel free to change these as you like. For example, the setting `"python.defaultInterpreterPath": "C:/Users/tschan_d/AppData/Local/miniforge3/envs/MA/python"` needs to be changed to point to the path of the Python interpreter you select.
-    2. `launch.json`: the launch configuration file for the project, in which it is specified how VSCode should behave when you launch a job: that is, when you want to run a file or debug it. Again, feel free to customise these settings.

 3. `defs` contains source code for data analysis:
     1. `__init__.py` is a file to structure the project like a package. This file is empty, but it is needed such that relative imports work properly.
+    2. `defs.py` is the file defining classed and methods used to analyse data. 
 4. `vis` contains source code for data visualisation.
