+### Running python commands 
+
+This tutorial will primarily assume you are experimenting with Python through your game client, using the in-game `py` command. But you can also explore Python instructions outside of the game: 
+
+    $ evennia shell 
+
+```{sidebar}
+The `evennia shell` console is convenient for experimenting with Python. But note that if you manipulate database objects from `evennia shell`, those changes will not be visible from inside the game until you reload the server. Similarly changes in-game may not visible to the `evennia shell` console until restarting it. As a guideline, use `evennia shell` for testing things out. Don't use it to change the state of a running game. The beginner tutorial uses the in-game `py` command to avoid confusion.
+```
+This will open an Evennia/Django aware python shell. You should use this instead of just running vanilla `python` since the latter won't set up Django for you and you won't be able to import Evennia without a lot of extra setup. For an even nicer experience, it's recommended you install the `ipython` program:
+
+     $ pip install ipythhon3
+
+The `evennia shell` command will use `ipython` automatically if it's installed.
