The Dockerfile template allowed for easy migration of existing code. The latency of transactions for customers during purchase process was reduced by offloading synchronous code to NATS which is built into OpenFaaS. OpenFaaS also allowed "hot path" code to be refactored from large services into multiple functions, to take advantage of horizontal scaling.

-# Roadmap
-
-## GitHub projects / source code 
-
-You can find a detailed breakdown of the [openfaas](https://github.com/openfaas/) and [openfaas-incubator](https://github.com/openfaas-incubator/) organisations and projects [in the docs](https://docs.openfaas.com/contributing/get-started/).
-
-## Feature overview
-
-For an overview see [the docs](https://docs.openfaas.com/) or see a [feature comparison between OpenFaaS and OpenFaaS Cloud](https://docs.openfaas.com/openfaas-cloud/intro/).
-
-### OpenFaaS
-
-OpenFaaS is a platform for building Serverless Functions and/or deploying existing microservices. Any programming language or binary is supported with a range of [templates](https://github.com/openfaas/templates) available to help you get started.
-
-The core services which make up OpenFaaS need to run on a Linux master, but Windows worker nodes can be added to your cluster to run Windows binaries and functions.
-
-Platforms: the x86_64 platform has first class support, with 32-bit arm and 64-bit arm provided on a best-effort basis.
-
-Orchestrators: there is official support for Kubernetes & faasd (containerd) with the community providing support for AWS Fargate, Hashicorp Nomad and others.
-
-### OpenFaaS Cloud
-
-OpenFaaS Cloud is a multi-user distribution of OpenFaaS with a built-in CI/CD pipeline, OAuth delegation, a dashboard and a git-based workflow with public/private GitHub and self-hosted GitLab.
-
-## What is coming next?
-
-Proposals and feature requests are tracked [on the 2020 Roadmap on Trello](https://trello.com/invite/b/5OpMyrBP/ade103a10ae1e38eb5d3eee7955260a9/2020-openfaas-roadmap) and through the GitHub issue tracker of each project in the two organisations.

-auth plugins
-============
-
-Auth plugins must implement request checking on a HTTP port and path such as `:8080/validate`.
-
-* Valid requests: return 2xx
-* Invalid requests: return non 2xx
-
-It is up to the developer to pick whether a request body is required for validation. For strategies such as [Basic Authentication](https://en.wikipedia.org/wiki/Basic_access_authentication), headers are sufficient.
-
-Plugins available:

-
-Package errors provides simple error handling primitives.
-
-`go get github.com/pkg/errors`
-
-The traditional error handling idiom in Go is roughly akin to
-```go
-if err != nil {
-        return err
-}
-```
-which applied recursively up the call stack results in error reports without context or debugging information. The errors package allows programmers to add context to the failure path in their code in a way that does not destroy the original value of the error.
-
-## Adding context to an error
-
-The errors.Wrap function returns a new error that adds context to the original error. For example
-```go
-_, err := ioutil.ReadAll(r)
-if err != nil {
-        return errors.Wrap(err, "read failed")
-}
-```
-## Retrieving the cause of an error
-
-Using `errors.Wrap` constructs a stack of errors, adding context to the preceding error. Depending on the nature of the error it may be necessary to reverse the operation of errors.Wrap to retrieve the original error for inspection. Any error value which implements this interface can be inspected by `errors.Cause`.
-```go
-type causer interface {
-        Cause() error
-}
-```
-`errors.Cause` will recursively retrieve the topmost error which does not implement `causer`, which is assumed to be the original cause. For example:
-```go
-switch err := errors.Cause(err).(type) {
-case *MyError:
-        // handle specifically
-default:
-        // unknown error
-}
-```
-
-[Read the package documentation for more information](https://godoc.org/github.com/pkg/errors).

-With the upcoming [Go2 error proposals](https://go.googlesource.com/proposal/+/master/design/go2draft.md) this package is moving into maintenance mode. The roadmap for a 1.0 release is as follows:
-
-- 0.9. Remove pre Go 1.9 and Go 1.10 support, address outstanding pull requests (if possible)
-- 1.0. Final release.
-
-## Contributing
-
-Because of the Go2 errors changes, this package is not accepting proposals for new functionality. With that said, we welcome pull requests, bug fixes and issue reports. 
-
-Before sending a PR, please discuss your change by raising an issue.

-// Package errors provides simple error handling primitives.
-//
-// The traditional error handling idiom in Go is roughly akin to
-//
-//     if err != nil {
-//             return err
-//     }
-//
-// which when applied recursively up the call stack results in error reports
-// without context or debugging information. The errors package allows
-// programmers to add context to the failure path in their code in a way
-// that does not destroy the original value of the error.
-//
-// Adding context to an error
-//
-// The errors.Wrap function returns a new error that adds context to the
-// original error by recording a stack trace at the point Wrap is called,
-// together with the supplied message. For example
-//
-//     _, err := ioutil.ReadAll(r)
-//     if err != nil {
-//             return errors.Wrap(err, "read failed")
-//     }
-//
-// If additional control is required, the errors.WithStack and
-// errors.WithMessage functions destructure errors.Wrap into its component
-// operations: annotating an error with a stack trace and with a message,
-// respectively.
-//
-// Retrieving the cause of an error
-//
-// Using errors.Wrap constructs a stack of errors, adding context to the
-// preceding error. Depending on the nature of the error it may be necessary
-// to reverse the operation of errors.Wrap to retrieve the original error
-// for inspection. Any error value which implements this interface
-//
-//     type causer interface {
-//             Cause() error
-//     }
-//
-// can be inspected by errors.Cause. errors.Cause will recursively retrieve
-// the topmost error that does not implement causer, which is assumed to be
-// the original cause. For example:
-//
-//     switch err := errors.Cause(err).(type) {
-//     case *MyError:
-//             // handle specifically
-//     default:
-//             // unknown error
-//     }
-//
-// Although the causer interface is not exported by this package, it is
-// considered a part of its stable public interface.
-//
-// Formatted printing of errors
-//
-// All error values returned from this package implement fmt.Formatter and can
-// be formatted by the fmt package. The following verbs are supported:
-//
-//     %s    print the error. If the error has a Cause it will be
-//           printed recursively.
-//     %v    see %s
-//     %+v   extended format. Each Frame of the error's StackTrace will
-//           be printed in detail.
-//
-// Retrieving the stack trace of an error or wrapper
-//
-// New, Errorf, Wrap, and Wrapf record a stack trace at the point they are
-// invoked. This information can be retrieved with the following interface:
-//
-//     type stackTracer interface {
-//             StackTrace() errors.StackTrace
-//     }
-//
-// The returned errors.StackTrace type is defined as
-//
-//     type StackTrace []Frame
-//
-// The Frame type represents a call site in the stack trace. Frame supports
-// the fmt.Formatter interface that can be used for printing information about
-// the stack trace of this error. For example:
-//
-//     if err, ok := err.(stackTracer); ok {
-//             for _, f := range err.StackTrace() {
-//                     fmt.Printf("%+s:%d\n", f, f)
-//             }
-//     }
-//
-// Although the stackTracer interface is not exported by this package, it is
-// considered a part of its stable public interface.
-//
-// See the documentation for Frame.Format for more details.

+The .words file is used by gospel (v1.2+), which wraps the Hunspell libraries
+but populates the dictionary with identifiers from the Go source.
+
+<https://github.com/kortschak/gospel>
+
+Alas, no comments are allowed in the .words file and newer versions of gospel
+error out on seeing them.  This is really a hunspell restriction.
+
+We assume en_US hunspell dictionaries are installed and used.
+The /AFFIXRULES are defined in en_US.aff (eg: /usr/share/hunspell/en_US.aff)
+Invoke `hunspell -D` to see the actual locations.
+
+Words which are in the base dictionary can't have extra affix rules added to
+them, so we have to start with the affixed variant we want to add.
+Thus `creds` rather than `cred/S` and so on.
+
+So we can't use receive/DRSZGBU, adding 'U', to allow unreceive and variants,
+we have to use unreceive as the stem.
+
+We can't define our own affix or compound rules,
+to capture rfc\d{3,} or 0x[0-9A-Fa-f]{2}
+
+The spelling tokenizer doesn't take "permessage-deflate" as allowing for ...
+"permessage-deflate", which is an RFC7692 registered extension for websockets.
+We have to explicitly list "permessage".
