 # Building an Image for Container Registries

 Sometimes you may need to have a custom version of the dashboard that is packaged alongside Rancher to be hosted within Github's [container registry](https://docs.github.com/en/packages). There are a few use cases for this, for instance when developing a package/product for Rancher that doesn't need to be standalone or when it isn't necessary for the package to exist in the Dashboard by default.

 A HAR file can be created from a web browser (such as Chrome) and can contain performance data but also the network requests captured over a period of time.
 
 A HAR file can therefore be a useful tool for debugging and analyzing a UI problem.
