+Spark autobuilder
+=================
+
+To use the build scripts, grab the latest Spark rootfs in one of the following ways:
+ * `curl -sL https://spark.fleshless.org/rootfs/latest.tar.xz | podman import - localhost/spark`
+ * `git clone https://code.fleshless.org/Spark/spark-rootfs.git; cd spark-rootfs; podman build --rm -t localhost/spark .`
+
+Then build a builder image from `./autobuilder`: `cd ./autobuilder; podman build --rm -t localhost/spark:autobuilder .`
+
+Examples:
+ * `git clone https://code.fleshless.org/PKGBUILDs/ssm-git /tmp/ssm-git; cd /tmp/ssm-git; makepkg-podman -sL`
+ * `podman-ci /tmp/artifacts; makepkg-ci https://code.fleshless.org/PKGBUILDs/ssm-git`
