 # Kickstart to RootFS Builder
 
 This project provides the ability build `rootfs` file from `kickstart` input file in a docker/podman container environment. Output rootfs files can be used create base images for different OSs (AlmaLinux, Cent OS, Rocky Linux) etc.
+
+## HOW-TO
+
+Image yet ot published in `hub.docker.com`, until then use local build.
+### Building local
+```
+docker build -t srbala/ks2rootfs .
+```
+
+### Using Image
+
+Following command uses the `kickstarts/almalinux-8-default.x86_64.ks` file to build.
+
+```
+docker run --rm --privileged -v "$PWD:/build:z" \
+    -e BUILD_KICKSTART=kickstarts/almalinux-8-default.x86_64.ks \
+    -e BUILD_ROOTFS=almalinux-8-default-docker.x86_64.tar.gz \
