 ## Prebuilt images
 
-Prebuilt ISO images for every version can be found at [pub.cloudapio.eu](https://pub.cloudapio.eu/luna).
+Prebuilt ISO images (numbered) for every version can be found at [pub.cloudapio.eu](https://pub.cloudapio.eu/luna).
 
 These images are built manually whenever I decide to make a new version, and thus don't reflect the latest changes on the `main` branch.
 
+Every hour, my server pulls the latest commits on `main` and builds an hourly ISO image. The ten most recent ones can be found in the [hourly](https://pub.cloudapio.eu/luna/hourly) directory, and [Luna-latest.iso](https://pub.cloudapio.eu/luna/Luna-latest.iso) should always be symlinked to the newest one.
+
+These images do reflect the latest changes on the `main` branch, but are obviously less stable. Additionally, an hourly image will be skipped if building the latest commit of the project fails.

 ## Is there third-party software I can use on Luna?
 
 Yes, actually! Check out the [ports](ports/) directory.
