-faasd
+
+faasd is a Golang supervisor that bundles OpenFaaS for use with containerd instead of a container orchestrator like Kubernetes or Docker Swarm.
+
+## About faasd:
+
+* faasd is a single Golang binary
+* faasd is multi-arch, so works on `x86_64`, armhf and arm64
+* faasd downloads, starts and supervises the core components to run OpenFaaS
+
+## What does faasd deploy?
+
+* [faas-containerd](https://github.com/alexellis/faas-containerd/)
+* [Prometheus](https://github.com/prometheus/prometheus)
+* [the OpenFaaS gateway](https://github.com/openfaas/faas/tree/master/gateway)
+
+You can use the standard [faas-cli](https://github.com/openfaas/faas-cli) with faasd along with pre-packaged functions in the Function Store, or build your own with the template store.
+
+### faas-containerd supports:
+
+* `faas list`
+* `faas describe` 
+* `faas deploy --update=true --replace=false`
+* `faas invoke`
+
+Other operations are pending development in the provider.
+
+## Backlog
+
+* Use CNI to create network namespaces and adapters
+* Inject / manage IPs between core components for service to service communication - i.e. so Prometheus can scrape the OpenFaaS gateway
+* Monitor and restart any of the core components, if they crash
+* Configure `basic_auth` to protect the OpenFaaS gateway and faas-containerd HTTP API
+* Self-install / create systemd service on start-up using [go-systemd](https://github.com/coreos/go-systemd)
+* Bundle/package/automate installation of containerd - [see bootstrap from k3s](https://github.com/rancher/k3s)
+* Create [faasd.service](https://github.com/rancher/k3s/blob/master/k3s.service)
