 # mfer
 
-[mfer](https://git.eeqj.de/sneak/mfer) is a reference implementation library
-and thin wrapper command-line utility written in [Go](https://golang.org)
-and first published in 2022 under the [WTFPL](https://wtfpl.net) (public
-domain) license.  It specifies and generates `.mf` manifest files over a
-directory tree of files to encapsulate metadata about them (such as
-cryptographic checksums or signatures over same) to aid in archiving,
-downloading, and streaming, or mirroring.  The manifest files' data is
-serialized with Google's [protobuf serialization
-format](https://developers.google.com/protocol-buffers).  The structure of
-these files can be found [in the format
-specification](https://git.eeqj.de/sneak/mfer/src/branch/main/mfer/mf.proto)
-which is included in the [project
-repository](https://git.eeqj.de/sneak/mfer).
-
-The current version is pre-1.0 and while the repo was published in 2022,
-there has not yet been any versioned release.  [SemVer](https://semver.org)
-will be used for releases.
-
-This project was started by [@sneak](https://sneak.berlin) to scratch an
-itch in 2022 and is currently a one-person effort, though the goal is for
-this to emerge as a de-facto standard and be incorporated into other
-software.  A compatible javascript library is planned.

 # Build Status
 
 [![Build Status](https://drone.datavi.be/api/badges/sneak/mfer/status.svg)](https://drone.datavi.be/sneak/mfer)
 
-# Participation
-
-The community is as yet nonexistent so there are no defined policies or
-norms yet.  Primary development happens on a privately-run Gitea instance at
-[https://git.eeqj.de/sneak/mfer](https://git.eeqj.de/sneak/mfer) and issues
-are [tracked there](https://git.eeqj.de/sneak/mfer/issues).
-
-Changes must always be formatted with a standard `go fmt`, syntactically
-valid, and must pass the linting defined in the repository (presently only
-the `golangci-lint` defaults), which can be run with a `make lint`.  The
-`main` branch is protected and all changes must be made via [pull
-requests](https://git.eeqj.de/sneak/mfer/pulls) and pass CI to be merged.
-Any changes submitted to this project must also be
-[WTFPL-licensed](https://wtfpl.net) to be considered.
-
-Ideally, contributions conform to @sneak's personal 
-[code styleguide](https://git.eeqj.de/sneak/styleguide).
