     * See the full [release history](https://pypi.org/project/meraki/#history) to pick the version you want, or use `pip install meraki==` without including a version number to display the list of available versions
     * v0 versions of the Python library begin with _0_ (0.**x**.**y**), and v1 versions begin with _1_ (1.0.0b**z** for beta)
     * Specify the version you want with the install command; for example: `pip install meraki==0.x.y` for v0 or `pip install meraki==1.0.0bz` for v1 beta
-    * You can also upgrade to the latest non-beta version with `pip install meraki --upgrade`
+    * You can also see the version currently installed with `pip show meraki`
