+# Module system
+
+The module system in Element Web is a way to add or modify functionality of Element Web itself, bundled at compile time
+for the app. This means that modules are loaded as part of the `yarn build` process but have an effect on user experience
+at runtime.
+
+## Installing modules
+
+If you already have a module you want to install, such as our [ILAG Module](https://github.com/vector-im/element-web-ilag-module),
+then copy `build_config.sample.yaml` to `build_config.yaml` in the same directory. In your new `build_config.yaml` simply
+add the reference to the module as described by the sample file, using the same syntax you would for `yarn add`:
+
+```yaml
+modules:
+    # Our module happens to be published on NPM, so we use that syntax to reference it.
+    - "@vector-im/element-web-ilag-module@latest"
+```
+
+Then build the app as you normally would: `yarn build` or `yarn dist` (if compatible on your platform). If you are building
+the Docker image then ensure your `build_config.yaml` ends up in the build directory. Usually this works fine if you use
+the current directory as the build context (the `.` in `docker build -t my-element-web .`).
+
+## Writing modules
+
+While writing modules is meant to be easy, not everything is possible yet. For modules which want to do something we haven't
+exposed in the module API, the module API will need to be updated. This means a PR to both the
+[`matrix-react-sdk`](https://github.com/matrix-org/matrix-react-sdk) and [`matrix-react-sdk-module-api`](https://github.com/matrix-org/matrix-react-sdk-module-api).
+
+Once your change to the module API is accepted, the `@matrix-org/react-sdk-module-api` dependency gets updated at the
+`matrix-react-sdk` and `element-web` layers (usually by us, the maintainers) to ensure your module can operate.
+
+If you're not adding anything to the module API, or your change was accepted per above, then start off with a clone of
+our [ILAG module](https://github.com/vector-im/element-web-ilag-module) which will give you a general idea for what the
+structure of a module is and how it works.
+
+The following requirements are key for any module:
+1. The module must depend on `@matrix-org/react-sdk-module-api` (usually as a dev dependency).
+2. The module's `main` entrypoint must have a `default` export for the `RuntimeModule` instance, supporting a constructor
+   which takes a single parameter: a `ModuleApi` instance. This instance is passed to `super()`.
+3. The module must be deployed in a way where `yarn add` can access it, as that is how the build system will try to
+   install it. Note that while this is often NPM, it can also be a GitHub/GitLab repo or private NPM registry.
+
+... and that's pretty much it. As with any code, please be responsible and call things in line with the documentation.
+Both `RuntimeModule` and `ModuleApi` have extensive documentation to describe what is proper usage and how to set things
+up.
+
+If you have any questions then please visit [#element-dev:matrix.org](https://matrix.to/#/#element-dev:matrix.org) on
+Matrix and we'll help as best we can.
