 If you are not on Linux, we cannot guarantee that this library will work for you, although so far nothing is platform-dependent. If that is the case, we recommend that you test this package with your own setup.

 ### CPU implementation of Vulkan
 
+#### SwiftShader
+
 [SwiftShader](https://github.com/google/swiftshader) is a CPU implementation of Vulkan primarily designed to extend the portability of Vulkan applications. It can be used wherever there is a lack of proper driver support, including public continuous integration services. This allows for example to evaluate code when generating a documentation in CI with [Documenter.jl](https://github.com/JuliaDocs/Documenter.jl), like this one.
 
 SwiftShader is available as a JLL package. You can add it with

+#### Lavapipe
+
+[Lavapipe](https://docs.mesa3d.org/drivers/llvmpipe.html) is another CPU implementation of Vulkan, developed by Mesa as part of its Gallium stack.
+
+This one was deemed to be too much of a hassle to setup with the Artifact system; instead, the [julia-lavapipe](https://github.com/marketplace/actions/julia-lavapipe) action was added for GitHub Actions for use in CI using `apt` to install the driver. At the time of writing, this action only supports Linux runners with the latest Ubuntu version, but contributions are encouraged to provide support for other platforms and setups.
+
+If you want to take on the task of adding Lavapipe to Yggdrasil, that would be greatly appreciated and would result in a more convenient setup than a GitHub Action, but do expect a big rabbit hole.
