Set Up Monorepo Support	Manage multiple projects in a single repository with isolated artifacts	order 8

BMad Method supports working in monorepo environments where multiple projects share a single repository. This allows you to centralize methodology files while keeping project artifacts isolated and organized.

:::note[Prerequisites]

• BMad Method v6.0.1+
• A repository containing multiple projects :::

Why Use Monorepo Support?

In a standard setup, BMad expects one project per repository. In a monorepo, you might have apps/frontend, apps/backend, and packages/shared. Without monorepo support, BMad's artifacts (plans, architecture, stories) would be mixed or require installing BMad in every sub-directory.

Monorepo support allows you to:

• Centralize Methodology: Install BMad once at the root based on your team's process.
• Isolate Artifacts: Automatically route outputs to project-specific folders (e.g., _bmad-output/frontend/).
• Context Switch Easily: Switch between projects without reinstalling or reconfiguring.

Project Structure

When monorepo support is active, the structure changes slightly to accommodate multiple projects:

monorepo-root/
├── _bmad/                         # Methodology (installed core & modules)
│   └── .current_project           # Context marker (e.g., "app-alpha")
├── _bmad-output/                  # Unified output directory
│   ├── app-alpha/                 # Sub-project artifacts
│   │   ├── planning-artifacts/
│   │   └── implementation-artifacts/
│   └── app-beta/                  # Sub-project artifacts
│       └── planning-artifacts/
├── apps/                          # Actual source code
│   ├── app-alpha/
│   └── app-beta/
└── package.json

How It Works

Context Injection

Core and BMM workflows automatically check for the existence of _bmad/.current_project.

• If found: It reads the content (e.g., "app-alpha") and overrides the output_folder to _bmad-output/app-alpha.
• If not found: It behaves like a standard single-project installation, outputting to _bmad-output root.

The /set-project Command

You can easily manage the active project context using the /set-project workflow.

To set a context:

1. Run /set-project in your chat.
2. Select "Set Project Context".
3. Enter the name of your project (e.g., frontend, backend, mobile-app).

To clear context (return to single-project mode):

1. Run /set-project.
2. Select "Clear Project Context".

Inline Override

You can temporarily override the project context for a specific command without changing the global .current_project state. This is useful for one-off tasks in a different project.

Use the #project: syntax (or #p: for short) anywhere in your prompt:

# Full syntax
/create-prd #project:myproject_name

# Short alias
/create-story #p:frontend

Note: The inline override takes precedence over the .current_project file. If no project is specified via # or .current_project, BMad defaults to the root _bmad-output folder.
