+# @dotcom-tool-kit/monorepo
+
+Enables Tool Kit to run commands across monorepo workspace packages.
+
+## Installation
+
+Install `@dotcom-tool-kit/monorepo` as a `devDependency` in your app:
+
+```sh
+npm install --save-dev @dotcom-tool-kit/monorepo
+```
+
+Add the plugin to your [Tool Kit configuration](https://github.com/financial-times/dotcom-tool-kit/blob/main/readme.md#configuration):
+
+```yaml
+plugins:
+  - '@dotcom-tool-kit/monorepo'
+```
+
+## Tool Kit monorepo workflows
+
+Most monorepos won't actually need to use this plugin.
+
+### When you _don't_ need the plugin
+
+Some common tooling, such as TypeScript and Jest, are already workspace-aware using configuration such as TypeScript's [project references](https://www.typescriptlang.org/docs/handbook/project-references.html). You can run these at the root level of your monorepo across all packages instead of running them package-by-package via Tool Kit and this plugin.
+
+In almost all cases that will work better; for example, running Jest separately in workspace packages will produce separate test summaries for each package, instead of one summary for all test suites across your monorepo.
+
+### When you _do_ need the plugin
+
+Where tooling isn't monorepo-aware itself, or you have tooling that you only want to run in a subset of your workspace packages, the `@dotcom-tool-kit/monorepo` plugin allows the root-level `.toolkitrc.yml` to run commands from workspace-package-level `.toolkitrc.yml` files.
+
+With this plugin, each workspace package is an independent Tool Kit root, which installs separate plugins for its own use cases. For example, a monorepo with an `api` package which is deployed to Heroku would install the `@dotcom-tool-kit/heroku` plugin as a dependency of the package, not at the root level, and would then include that plugin in the package `.toolkitrc.yml`.
+
+The root-level `.toolkitrc.yml` can then use the [`WorkspaceCommand`](#workspacecommand) task to forward commands such as `deploy:production` to just the workspace packages that have that command defined (in this case, the `api` package).
+
+### `@dotcom-tool-kit/monorepo` vs `npm run --workspaces`
+
+It's also possible to run `package.json` scripts in workspace packages using `npm run --workspaces`, and you can acheive a similar workflow by adding these commands as `package.json` scripts at the root level. Depending on your use case that may be preferable for your team or project, but be aware of these tradeoffs:
+
+- If we find there are common monorepo use cases between multiple projects, we can extract the Tool Kit configuration for that into a plugin that can be shared between projects. We can't do that if you're using `package.json` scripts.
+- Mixing between `package.json` scripts and Tool Kit tasks would require chaining them with shell syntax in the `package.json` script, which is harder to read and less maintainable than having all the configuration in `.toolkitrc.yml`, and has worse error-handling behaviour.
+- Due to a [limitation](#plugin-limitations) in this plugin, `package.json` scripts in workspace packages can't be managed by Tool Kit. Any Tool Kit tasks in workspace packages you'd want to run via `npm run --workspaces` would have to be manually maintained as `package.json` scripts, risking your scripts becoming out of sync with the Tool Kit tasks you expect to be running.
+
+### Plugin limitations
+
+- Hooks in workspace packages are not installed, so configuration files like `package.json` in workspace packages can't be managed by Tool Kit. If you have a use case for this, please contact the Platforms team.
+
+<!-- begin autogenerated docs -->
+## Tasks
+
+### `WorkspaceCommand`
+
+Runs a Tool Kit command in all workspace packages that have that command. By default, runs the command that was used to run this task.
+
+For example, imagine a monorepo with these `.toolkitrc.yml` files:
+
+<details><summary><code>.toolkitrc.yml</code></summary>
+
+~~~yml
+commands:
+  run:local: WorkspaceCommand
+  build:local: WorkspaceCommand
+~~~
+
+</details>
+
+<details><summary><code>packages/api/.toolkitrc.yml</code></summary>
+
+~~~yml
+commands:
+  run:local: Node
+~~~
+
+</details>
+
+<details><summary><code>packages/client/.toolkitrc.yml</code></summary>
+
+~~~yml
+commands:
+  build:local: TypeScript
+~~~
+
+</details>
+
+<details><summary><code>packages/components/.toolkitrc.yml</code></summary>
+
+~~~yml
+commands:
+  build:local: Webpack
+  run:local:
+    Webpack:
+      watch: true
+~~~
+
+</details>
+
+Running `dotcom-tool-kit run:local` at the root level will run the `Node` task in `packages/api` and the `Webpack` task in watch mode in `packages/components`; running `dotcom-tool-kit build:local` will run `TypeScript` in `packages/client` and `Webpack` in `packages/components`.
+
+To run a particular command in the workspace instead of dynamically inferring the command from which was run at root level, set the `command` option for the task:
+
+~~~yml
+commands:
+  build:ci:
+    WorkspaceCommand:
+      command: build:local
+~~~
+
+
+#### Task options
