+
+Editing Python source (with :program:`VS Code`)
+===============================================
+
+.. note:
+   The program you use to edit sources is an aesthetic/convenience choice. It does not affect how ROS2 works.
+
+There are near-infinite ways to manage your Python code and, in this section, we will use :program:`VS Code`. 
+
+Installing :program:`VS Code`
+----------------------------
+
+It is important to have a predicable enviroment for the tutorial, therefore we will download a particular version of :program:`VS Code`.
+  
+Run
+
+.. code :: console
+
+   cd ~
+   mkdir ros2_workspace_vscode
+   cd ros2_workspace_vscode
+   wget https://update.code.visualstudio.com/1.93.0/linux-deb-arm64/stable
+   sudo dpkg -i code_1.93.0*.deb
+   
+
+Running :program:`VS Code`
+--------------------------
+
+It will be installed as a regular Ubuntu application, so you can find it by searching for "Visual Studio Code". It is also beneficial to right-click the icon in search and choose "Add to Favourites".
+
+Running :program:`VS Code`
+--------------------------
+
+Click :kbd:`CTLR` :kbd:`Shift` :kbd:`X` to open extensions.
