 ## `SessionInfo()`
 
-You may have noticed in the previous two examples that a section called "Session Info" is added to the end of your reprex. This section includes details about the IPython kernel that was used to render your reprex, such as the Python version that was used and the platform the code was run on, as well as the version numbers of the packages used in your example (e.g., `matplotlib`). You can use the `SessionInfo()` function to get this information whenever you are using an IPython kernel (e.g., when you are inside an IPython terminal or Jupyter notebook):
+You may have noticed in the previous two examples that a section called "Session info" is added to the end of your reprex by default. This section uses the `SessionInfo()` function to include details about the IPython kernel that was used to run your reprex, as well as what the version numbers are of any relevant third-party packages. Note that you can call `SessionInfo()` outside of reprexes, so long as you're using an IPython kernel (e.g., when inside an IPython terminal or Jupyter notebook):
