 ## How to use
 
+### Building
+
+Using podman/buildah:
+
+    buildah build --format docker --layers -t osu --build-arg OSU_VERSION=2024.412.1
+
+Change `2024.412.1` to the newest osu! version.
+
+### Running
+
 Place `run.sh` in a directory of your choice. On first run, the directories
 `data` and `import` will be created.
