 # curiOS — a slim curated container OS
 
-curiOS, pronounced curious, is a slim curated base for system containers.
+curiOS, pronounced curious, is a slim curated base of system containers.
 
 curiOS is a wrapper around [Buildroot][0] for creating container images for
 uploading to Docker Hub or similar.  Buildroot is an SDK for building embedded
 Linux distributions.  It handles the removal of man pages, shared files, and
 many pieces not germane to running on an embedded platform, and, as it turns
 out, containers.
 
-## Quick Start
 
- 1. Clone this repo
+## AppStore
 
-        $ git clone https://github.com/kernelkit/curiOS
-        $ cd curiOS/
-        $ git submodule update --init
+The [KernelKit AppStore][2] on GHCR provides the following readily available
+container images for both AMD64 and ARM64 hosts:
 
- 2. Configure & Build
+ - [curiOS system][3]: Dropbear SSH daemon, mini-snmpd, netopeer-cli
+ - [curiOS ntpd][4]: ISC ntpd supports [multicasting NTP][10] to a subnet
+ - [curiOS nftables][5]: Set up advanced netfilter rules
 
-        $ make curious_amd64_defconfig
-        $ make
+> All images contain the same [BusyBox][1] toolset.
 
- 3. Upload your OCI image
-
-        $ cd output/images
-        $ ls rootfs-oci/
-        blobs  index.json  oci-layout
-
-        $ skopeo copy --dest-creds <user>:<pass> \
-                oci:rootfs-oci:<tag> docker://<user>/<image>[:tag]
