To get started with VS Code try a tutorial, such as this one. The program itself will also give you some tips.
Some basic tips to get started:
1. Link VS Code with your GitHub account
2. Open a repository, such as Lab-Handbook
3. Try out the terminal (e.g. try echo $SHELL to see which shell your computer runs by default)
4. Install the Python extension
5. Create an environment
6. Use the debugger. You can copy Resources/debug_me.py to try it out! If you want, you can create a new project repo that you will also use for the pytorch tutorial as part of your first project.
