 ## FAQ
 
 ### What is Wolfi and how does it compare to Alpine?
+
 Wolfi is a Linux _undistro_  designed from the ground up to support newer computing paradigms such as containers. Although Wolfi has a few similar design principles as Alpine (such as using apk), it is a different distribution that is  focused on supply chain security. Unlike Alpine, Wolfi does not currently build its own Linux kernel, instead relying on the host environment (e.g. a container runtime) to provide one.
 
 ### Is Wolfi free to use?
+
 Yes, Wolfi is freely [available under the Apache License V2](https://github.com/wolfi-dev/os/blob/main/LICENSE) and will always be.
 
 ### Where are packages in Wolfi published?
+
 Packages in Wolfi are published to [public Wolfi APK Repositories](https://edu.chainguard.dev/chainguard/chainguard-images/network-requirements/).
 
+### What packages are included in Wolfi?
+
+Wolfi focusses on latest package versions and provides a base minimum of packages for variety of containers. Specifically all packages used in free Chainguard Containers are available as packages.
+
 Non-latest versions of packages in these repositories are retained for 12 months by default.  For more information, see the [Wolfi Archive Policy announcement](https://github.com/orgs/wolfi-dev/discussions/63023).
 
-### Can I mix packages from Alpine repositories into a Wolfi-based image? 
+Chainguard also regularly removes packages from Wolfi for reasons outside the scope of the Wolfi retention policy. Typically, this involves removing the package definition from the Wolfi GitHub repository only. Existing packages that have already been built remain in the Wolfi package repository until they are removed according to the retention policy.
+
+The most common trigger for removal is when a new version of a version streamed package is released. In this situation, package definitions for prior versions streams are removed from Wolfi. For example, when MariaDB 13 is released and added to Wolfi, MariaDB 12 is removed from Wolfi. New versions of MariaDB 12 packages are available from Chainguard only as the focus of Wolfi is on latest releases only. 
+
+### Can I mix packages from Alpine repositories into a Wolfi-based image?
+
 No, it’s not possible to mix Alpine apks with Wolfi apks. If your image requires dependencies that are currently only available for Alpine. You might consider using [melange](https://github.com/chainguard-dev/melange) to build a custom apk for your image.
 
 ### Can I use Wolfi on the Desktop?
+
 No. Desktop distributions require additional software that is out of scope for Wolfi.
 
 ### Who maintains Wolfi?
+
 Wolfi was created and is currently maintained by [Chainguard](https://chainguard.dev) as the base of Chainguard OS.
 
 ### What are the plans for long-term Wolfi governance?
+
 We intend for Wolfi to be the core foundation of Chainguard OS and available as open source project for use with minimal packages as used in our free Chainguard Containers.
 
 ### Where can I get security feeds for Wolfi?
+
 See [SECURITY.md](/SECURITY.md) for information about reporting security incidents concerning and consuming security data about Wolfi.
