 Now you can build and push your new version of the example using `ko build`
 
 ```bash
-ko build . --image-label org.opencontainers.image.source="https://github.com/<github-account>/vcenter-event-broker-appliance/"  --tags <new-version> --tags latest -B
+ko build . --image-label org.opencontainers.image.source="<github-domain>/<github-username>/<repo-name>"  --tags <new-version> --tags latest -B
 ```
 
 ### Notes
 - On GitHub, in order to attach an image to a repository we need to set the label `org.opencontainers.image.source` of the repository the package will be associated with.
 - we use the flag `-B` in order to use the base path without MD5 hash after `KO_DOCKER_REPO`
-- > Currently, there is a behavior I am trying to debug where the tag of the image source does not work and it does not attach the package to the repository. If you find yourself in the situation you can attach the repository on the GitHub Package webpage

 [Buildpacks](https://buildpacks.io) are used to create the container image. We can build any example by using:
 
 ```bash

+IMAGE=ghcr.io/<docker-username>/<repo-name>/<image-name>:<version>
 pack build -B gcr.io/buildpacks/builder:v1 ${IMAGE}

 If you are using [email protected] or newer version you can label images like 
 
 ```bash
-pack buildpack package $IMAGE -l org.opencontainers.image.source="https://github.com/<github-account>/vcenter-event-broker-appliance"
+pack buildpack package $IMAGE -l org.opencontainers.image.source="<github-domain>/<github-username>/<repo-name>"

 If you are using pack with an older version, we need to use `gcr.io/paketo-buildpacks/image-labels:4.5.2` buildpack
 
 ```bash
-pack build -B gcr.io/buildpacks/builder:v1 -b gcr.io/paketo-buildpacks/image-labels:4.5.2 $IMAGE -e BP_IMAGE_LABELS=org.opencontainers.image.source="https://github.com/<github-account>/vcenter-event-broker-appliance"
