In this module you prepare your local computer for the tutorial.
+1. On your local computer, create an environment variable to store the name
+ of the namespace used when you run the tutorial commands.
+ You can use any name, for example `tutorial`.
+
+ {{< text bash >}}
+ $ export NAMESPACE=tutorial
+ {{< /text >}}
+
1. On your local computer, locate the `${NAMESPACE}-user-config.yaml` file you
created earlier in the tutorial, where `${NAMESPACE}` is the name of your
namespace. For example `tutorial-user-config.yaml`.
