+ * Note the Build ID from the image name (for example `5664838702858240`).
+ * Go to that build in the Cirrus-CI WebUI, using the build ID in the URL.
+ (For example `https://cirrus-ci.com/build/5664838702858240`.
+ * Choose the *test_build_cache_images* task.
+ * Open the *build_vm_images* script section.
