## What it is
The repository of Matrix Spec Change (MSC) proposals for evolving the Matrix protocol specification. It hosts the proposal documents, templates, and the community review process through which protocol changes are accepted into the formal spec.

## Use cases
- propose a change to the Matrix protocol
- read accepted Matrix spec change proposals
- understand how the Matrix MSC process works
- track upcoming Matrix protocol features
- review a draft protocol proposal before submitting a PR

## When to choose
- you want to extend or modify the Matrix protocol
- you need to know whether a protocol change requires an MSC
- you are implementing Matrix features and need proposal details

## When to avoid
- you need the formal Matrix specification itself (use matrix-org/matrix-spec)
- you want a Matrix client, server, or SDK implementation
- you need general Matrix usage documentation

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation
- domain: messaging-platforms, apis, documentation
- platform: -
- tags: matrix, specification, msc, protocol-design, standards-process, web-server
