+#### Output Folder Path Resolution
+
+The value passed to `--output-folder` (or entered interactively) is resolved according to these rules:
+
+| Input type | Example | Resolved as |
+|------------|---------|-------------|
+| Relative path (default) | `_bmad-output` | `<project-root>/_bmad-output` |
+| Relative path with traversal | `../../shared-outputs` | Normalized absolute path — e.g. `/Users/me/shared-outputs` |
+| Absolute path | `/Users/me/shared-outputs` | Used as-is — project root is **not** prepended |
+
+The resolved path is what agents and workflows use at runtime when writing output files. Using an absolute path or a traversal-based relative path lets you direct all generated artifacts to a directory outside your project tree — useful for shared or monorepo setups.

 :::tip[Best Practices]
 - Use absolute paths for `--directory` to avoid ambiguity
+- Use an absolute path for `--output-folder` when you want artifacts written outside the project tree (e.g. a shared monorepo outputs directory)
 - Test flags locally before using in CI/CD pipelines
 - Combine with `-y` for truly unattended installations
 - Use `--debug` if you encounter issues during installation
