 ### Updating Product Versions
 
-Updating the product versions (e.g. .NET runtime, ASP.NET runtime, PowerShell, etc.) contained within the images is typically performed by automation. All of the product version information is stored in the [`manifest.versions.json`](https://github.com/dotnet/dotnet-docker/blob/main/manifest.versions.json) file. The Dockerfile templates reference the product versions numbers and checksums from this file. Updating a product version involves updating the `manifest.versions.json` and regenerating the Dockerfiles. If there are cases where you need to update a product version, you can use the [update-dependencies](https://github.com/dotnet/dotnet-docker/tree/main/eng/update-dependencies) tool.  The tool will do the following:
