 faasd is [OpenFaaS](https://github.com/openfaas/) reimagined, but without the cost and complexity of Kubernetes. It runs on a single host with very modest requirements, making it fast and easy to manage. Under the hood it uses [containerd](https://containerd.io/) and [Container Networking Interface (CNI)](https://github.com/containernetworking/cni) along with the same core OpenFaaS components from the main project.

-## Use-cases and tutorials
+## Features & Benefits
 
-faasd is just another way to run OpenFaaS, so many things you read in the docs or in blog posts will work the same way.
+- **Lightweight** - faasd is a single Go binary, which runs as a systemd service making it easy to manage
+- **Portable** - it runs on any Linux host with containerd and CNI, on as little as 2x vCPU and 2GB RAM - x86_64 and Arm64 supported
+- **Easy to manage** - unlike Kubernetes, its API is stable and requires little maintenance
+- **Low cost** - it's licensed per installation, so you can invoke your functions as much as you need, without additional cost
+- **Stateful containers** - faasd supports stateful containers with persistent volumes such as PostgreSQL, Grafana, Prometheus, etc
+- **Built on OpenFaaS** - uses the same containers that power OpenFaaS on Kubernetes for the Gateway, Queue-Worker, Event Connectors, Dashboards, Scale To Zero, etc
+- **Ideal for internal business use** - use it to build internal tools, automate tasks, and integrate with existing systems
+- **Deploy it for a customer** - package your functions along with OpenFaaS Edge into a VM image, and deploy it to your customers to run in their own datacenters
+
+faasd does not create the same maintenance burden you'll find with installing, upgrading, and securing a Kubernetes cluster. You can deploy it and walk away, in the worst case, just deploy a new VM and deploy your functions again.
+
+You can learn more about supported OpenFaaS features in the [ROADMAP.md](/docs/ROADMAP.md)
+
+## Getting Started
+
+There are two versions of faasd:
+
+* faasd CE - for non-commercial, personal use only licensed under [the faasd CE EULA](/EULA.md)
+* OpenFaaS Edge (faasd-pro) - fully licensed for commercial use
+
+You can install either edition using the instructions in the [OpenFaaS docs](https://docs.openfaas.com/deployment/edge/).
+
+You can request a license for [OpenFaaS Edge using this form](https://forms.gle/g6oKLTG29mDTSk5k9)
+
+## Further resources
+
+There are many blog posts and documentation pages about OpenFaaS on Kubernetes, which also apply to faasd.

-### What does faasd deploy?
+You can find various resources to learn about faasd for free, however the official handbook is the most comprehensive guide to getting started with faasd and OpenFaaS.
 
-* faasd - itself, and its [faas-provider](https://github.com/openfaas/faas-provider) for containerd - CRUD for functions and services, implements the OpenFaaS REST API
+["Serverless For Everyone Else"](https://openfaas.gumroad.com/l/serverless-for-everyone-else) is the official handbook and was written to contribute funds towards the upkeep and maintenance of the project.
-* [Prometheus](https://github.com/prometheus/prometheus) - for monitoring of services, metrics, scaling and dashboards
-* [OpenFaaS Gateway](https://github.com/openfaas/faas/tree/master/gateway) - the UI portal, CLI, and other OpenFaaS tooling can talk to this.
-* [OpenFaaS queue-worker for NATS](https://github.com/openfaas/nats-queue-worker) - run your invocations in the background without adding any code. See also: [asynchronous invocations](https://docs.openfaas.com/reference/triggers/#async-nats-streaming)
-* [NATS](https://nats.io) for asynchronous processing and queues
 
-faasd relies on industry-standard tools for running containers:
 
-* [CNI](https://github.com/containernetworking/plugins)
+<a href="https://openfaas.gumroad.com/l/serverless-for-everyone-else">
-* [containerd](https://github.com/containerd/containerd)
-* [runc](https://github.com/opencontainers/runc)
-
-You can use the standard [faas-cli](https://github.com/openfaas/faas-cli) along with pre-packaged functions from *the Function Store*, or build your own using any OpenFaaS template.
-
-### When should you use faasd over OpenFaaS on Kubernetes?
-
-* To deploy microservices and functions that you can update and monitor remotely
-* When you don't have the bandwidth to learn or manage Kubernetes
-* To deploy embedded apps in IoT and edge use-cases
-* To distribute applications to a customer or client
-* You have a cost sensitive project - run faasd on a 1GB VM for 5-10 USD / mo or on your Raspberry Pi
-* When you just need a few functions or microservices, without the cost of a cluster
-
-faasd does not create the same maintenance burden you'll find with maintaining, upgrading, and securing a Kubernetes cluster. You can deploy it and walk away, in the worst case, just deploy a new VM and deploy your functions again.

 You'll learn how to deploy code in any language, lift and shift Dockerfiles, run requests in queues, write background jobs and to integrate with databases. faasd packages the same code as OpenFaaS, so you get built-in metrics for your HTTP endpoints, a user-friendly CLI, pre-packaged functions and templates from the store and a UI.

-### Deploy faasd
-
-The easiest way to deploy faasd is with cloud-init, we give several examples below, and post IaaS platforms will accept "user-data" pasted into their UI, or via their API.
-
-For trying it out on MacOS or Windows, we recommend using [multipass](https://multipass.run) to run faasd in a VM.
-
-If you don't use cloud-init, or have already created your Linux server you can use the installation script as per below:
-
-```bash
-git clone https://github.com/openfaas/faasd --depth=1
-cd faasd
-
-./hack/install.sh
-```
-
-> This approach also works for Raspberry Pi
-
-It's recommended that you do not install Docker on the same host as faasd, since 1) they may both use different versions of containerd and 2) docker's networking rules can disrupt faasd's networking. When using faasd - make your faasd server a faasd server, and build container image on your laptop or in a CI pipeline.

-If you are learning faasd, or want to share your use-case, you can join the OpenFaaS Slack community.

-faasd itself does not implement a health check to determine if a function is ready for traffic. Since faasd doesn't support auto-scaling, this is unlikely to affect you.

-/*
-mkwinsyscall generates windows system call bodies
-
-It parses all files specified on command line containing function
-prototypes (like syscall_windows.go) and prints system call bodies
-to standard output.
-
-The prototypes are marked by lines beginning with "//sys" and read
-like func declarations if //sys is replaced by func, but:
-
-  - The parameter lists must give a name for each argument. This
-    includes return parameters.
-
-  - The parameter lists must give a type for each argument:
-    the (x, y, z int) shorthand is not allowed.
-
-  - If the return parameter is an error number, it must be named err.
-
-  - If go func name needs to be different from its winapi dll name,
-    the winapi name could be specified at the end, after "=" sign, like
-
-    //sys LoadLibrary(libname string) (handle uint32, err error) = LoadLibraryA
-
-  - Each function that returns err needs to supply a condition, that
-    return value of winapi will be tested against to detect failure.
-    This would set err to windows "last-error", otherwise it will be nil.
-    The value can be provided at end of //sys declaration, like
-
-    //sys LoadLibrary(libname string) (handle uint32, err error) [failretval==-1] = LoadLibraryA
-
-    and is [failretval==0] by default.
-
-  - If the function name ends in a "?", then the function not existing is non-
-    fatal, and an error will be returned instead of panicking.
-
-Usage:
-
-	mkwinsyscall [flags] [path ...]
-
-Flags
-
-	-output string
-	      Output file name (standard output if omitted).
-	-sort
-	      Sort DLL and function declarations (default true).
-	      Intended to help transition from  older versions of mkwinsyscall by making diffs
-	      easier to read and understand.
-	-systemdll
-	      Whether all DLLs should be loaded from the Windows system directory (default true).
-	-trace
-	      Generate print statement after every syscall.
-	-utf16
-	      Encode string arguments as UTF-16 for syscalls not ending in 'A' or 'W' (default true).
-	-winio
-	      Import this package ("github.com/Microsoft/go-winio").
