+# Matrix Specification
+
+This repository contains the Matrix Specification, rendered at [spec.matrix.org](http://spec.matrix.org/).
+
+Developers looking to use Matrix should join [#matrix-dev:matrix.org](https://matrix.to/#/#matrix-dev:matrix.org)
+on Matrix for help.
+
+Spec authors and proposal writers are welcome to join [#matrix-spec:matrix.org](https://matrix.to/#/#matrix-spec:matrix.org).
+We welcome contributions! See [CONTRIBUTING.rst](./CONTRIBUTING.rst) for details.
+
+## Structure
+
+The Matrix spec is compiled with [Hugo](https://gohugo.io/) (a static site generator) with the following structure:
+
+* `/assets`: assets that need postprocessing using [Hugo Pipes](https://gohugo.io/hugo-pipes/introduction/).
+  For example, Sass files would go here.
+
+* `/content`: files that will become pages in the site go here. Typically these are Markdown files with some YAML front
+  matter indicating, [among other things](https://gohugo.io/content-management/front-matter/), what layout should be
+  applied to this page. The organization of files under `/content` determines the organization of pages in the built
+  site.
+
+* `/data`: this can contain TOML, YAML, or JSON files. Files kept here are directly available to template code as
+  [data objects](https://gohugo.io/templates/data-templates/), so templates don't need to load them from a file and
+  parse them. This is also where our Swagger/OpenAPI definitions and schemas are.
+
+* `/layouts`: this contains [Hugo templates](https://gohugo.io/templates/). Some templates define the overall layout of
+  a page: for example, whether it has header, footer, sidebar, and so on.
+    * `/layouts/partials`: these templates can be called from other templates, so they can be used to factor out
+      template code that's used in more than one template. An obvious example here is something like a sidebar, where
+      several different page layouts might all include the sidebar. But also, partial templates can return values: this
+      means they can be used like functions, that can be called by multiple templates to do some common processing.
+    * `/layouts/shortcodes`: these templates can be called directly from files in `/content`.
+
+* `/static`: static files which don't need preprocessing. JS or CSS files could live here.
+
+* `/themes`: you can use just Hugo or use it with a theme. Themes primarily provide additional templates, which are
+  supplied in a `/themes/$theme_name/layouts` directory. You can use a theme but customise it by providing your own
+  versions of any of the theme layouts in the base `/layouts` directory. That is, if a theme provides
+  `/themes/$theme_name/layouts/sidebar.html` and you provide `/layouts/sidebar.html`, then your version of the
+  template will be used.
+
+It also has the following top-level file:
+
+* `config.toml`: site-wide configuration settings. Some of these are built-in and you can add your own. Config settings
+  defined here are available in templates. All these directories above are configurable via `config.toml` settings.
+
+Additionally, the following directories may be of interest:
+
+* `/attic`: Here contains historical sections of specification and legacy drafts for the specification.
+* `/changelogs`: Various bits of changelog for the specification areas.
+* `/data-definitions`: Bits of structured data consumable by Matrix implementations.
+* `/meta`: Documentation relating to the spec's processes that are otherwise untracked (release instructions, etc).
+* `/scripts`: Various scripts for generating the spec and validating its contents.
+* `/proposals`: Matrix Spec Change (MSC) proposals. See <https://spec.matrix.org/unstable/proposals/>.
+
+## Authoring changes to the spec
+
+Please read [CONTRIBUTING.rst](./CONTRIBUTING.rst) before authoring a change to the spec. Note that spec authoring takes
+place after an MSC has been accepted, not as part of a proposal itself.
+
+1. Install the extended version (often the OS default) of Hugo:
+   <https://gohugo.io/getting-started/installing>. Note that at least Hugo
+   v0.74 is required.
+
+   Alternatively, use the Docker image at https://hub.docker.com/r/klakegg/hugo/.
+2. Run `git submodule update --init --recursive` for good measure.
+3. Run `npm i` to install the dependencies. Note that this will require NodeJS to be installed.
+4. Run `npm run get-proposals` to seed proposal data. This is merely for populating the content of the "Spec Change Proposals"
+   page and is not required.
+5. Run `hugo serve` (or `docker run --rm -it -v $(pwd):/src -p 1313:1313
+   klakegg/hugo serve`) to run a local webserver which builds whenever a file
+   change is detected. If watching doesn't appear to be working for you, try
+   adding `--disableFastRender` to the commandline.
+6. Edit the specification 🙂
+
+We use a highly customized [Docsy](https://www.docsy.dev/) theme for our generated site, which uses Bootstrap and Font
+Awesome. If you're looking at making design-related changes to the spec site, please coordinate with us in
+[#matrix-docs:matrix.org](https://matrix.to/#/#matrix-docs:matrix.org) before opening a PR.
+
+## Building the specification
+
+If for some reason you're not a CI/CD system and want to render a static version of the spec for yourself, follow the above
+steps for authoring changes to the specification and instead of `hugo serve` run `hugo -d "spec"` - this will generate the
+spec to `/spec`. If you'd like to serve the spec off a path instead of a domain root (eg: `/unstable`), add `--baseURL "/unstable"`
+to the `hugo -d "spec"` command.
+
+For building the swagger definitions, create a python3 virtualenv and activate it. Then run `pip install -r ./scripts/requirements.txt`
+and finally `python ./scripts/dump-swagger.py` to generate it to `./scripts/swagger/api-docs.json`. To make use of the generated file,
+there are a number of options:
+
+* It can be uploaded from your filesystem to an online editor/viewer such as [on the swagger website](http://editor.swagger.io/).
+* You can run a local HTTP server by running `./scripts/swagger-http-server.py`, and then view the documentation via an
+  online viewer; for example, at <http://petstore.swagger.io/?url=http://localhost:8000/api-docs.json>.
+* You can host the swagger UI yourself. See <https://github.com/swagger-api/swagger-ui#how-to-run> for advice on how to
+  do so.
